A Vision Becomes Reality

The roots of exTra run deep: The name and the fundamental concept for this musical project were conceived as far back as 1990. However, the vision had to remain dormant for over three decades, as the means to realize it simply didn't exist.

Behind exTra is producer Tom Heinz. Although he does not play a traditional instrument himself, he never gave up on the dream of having his own band. Only today, in the age of artificial intelligence, has he found the tools to finally make his ideas audible.

exTra is a modern AI band — and that changes everything. A traditional band is limited by what its members can play. exTra is not. Thanks to AI, the entire spectrum of musical styles is available: any instrument, any genre, any era. The music always serves the concept — not the other way around.

exTra makes concept albums, each one built around a single idea, a world, a question. The genre follows from the story. The debut "The Iron Wheel" traced the rise and fall of world civilizations. The second album "Confoederatio" told the story of Switzerland. And the next album will take the concept somewhere entirely new.

Confoederatio

"Confoederatio" tells the story of Switzerland through the voices of those who shaped it. Each of the ten songs is narrated by a different historical figure, offering a deeply personal perspective on the events that shaped the nation. Musically, the album moves from Dark 70s Swiss Folk Rock through Liedermacher chanson, Gründerzeit shuffle, Glenn Miller Big Band swing, to ABBA-inspired disco.

The Iron Wheel

A concept album about the cycle of human civilizations. The listener is guided through the eyes of different cultures across millennia. The "Iron Wheel" is the common thread — it crushes the old to make way for the new. From Sumer to the British Empire: eleven tracks, one unbroken arc of history.

Nine — The Next Chapter

After The Iron Wheel swept across millennia of world history, and Confoederatio turned inward to trace a single nation's soul — what comes next?

A number. A word. Nine.

Nine is everywhere, once you start looking. There are nine planets, if you count generously. Nine circles of descending depth. Nine lives. Nine Beethoven symphonies. Nine is the highest single digit — the last step before everything resets and begins again. In many traditions, it is the number of completion: wisdom accumulated through experience. In others, a warning. The moment before the wheel turns.

exTra's third concept album takes the same approach as its predecessors: one idea, one world, one question. But where The Iron Wheel looked outward across civilizations, and Confoederatio looked inward at one country's story — Nine looks somewhere else entirely.

We're not saying more. Not yet.

What we can say: the genre will surprise you. The concept is tight. And once you hear it, the number will mean something different to you than it did before.

Nine arrives in 2026.

From the World Stage to Swiss Ground — "Confoederatio" Is Here

When "The Iron Wheel" was released in December 2025, it traced the arc of human history from Sumer to the British Empire. It was a journey outward — across oceans, deserts, and centuries. Now, exTra turns inward.

"Confoederatio" is the second concept album by exTra, and it does what no one expected: it tells the entire story of Switzerland in ten songs. From the mythological whisper of Helvetia to the algorithm-driven present, each track is narrated by a historical figure — in their own voice, from their own time.

The concept is simple but ambitious: one country, one thousand years, ten perspectives. A goddess. A Roman emperor. A rebel with a crossbow. A mercenary bleeding in foreign mud. A hermit who saved a nation with a single sentence. Two brothers on opposite sides of a religious war. A court clerk who became Europe's first whistleblower. A visionary who built modern Switzerland and was discarded by it. A woman who watched her country hide behind mountains. And finally — a modern Swiss voice, asking: where do we go from here?

Musically, the album is a deliberate departure from the signature Dark 70s Swiss Folk Rock sound. While the core identity — Stratocaster, Swiss Accordion, Brass — anchors several tracks, the album deliberately breaks its own rules. Song 7 trades electric guitar for nylon strings and a Liedermacher warmth. Song 8 replaces the Stratocaster entirely with an upright piano and a Gründerzeit shuffle. Song 9 is a full Glenn Miller-style Big Band swing — with a woman's voice where you'd expect a general. And Song 10 closes the album with an ABBA-inspired disco groove, saxophone solos, and a choir that fades out with a smile.

Every song was produced using AI-assisted composition (Suno), with extensive post-production in Logic Pro. The lyrics were developed through deep historical research, ensuring that every verse is rooted in documented events.

"Confoederatio" is available now on all major streaming platforms. The story goes on.

Song List

The Album "Confoederatio" (2026)

"Confoederatio" tells the story of Switzerland through the voices of those who shaped it. Each of the ten songs is narrated by a historical figure — from the mythological mother of the nation to a modern Swiss citizen asking where the country goes next. The album spans over a thousand years of Swiss history, from Roman conquest to the age of artificial intelligence.

Track 1 · The Origin

Stone and Water (Helvetia)

Helvetia herself speaks — the mythological mother of Switzerland. She has watched glaciers carve the valleys, legions march through snow, and sons leave for foreign wars. Her voice is a whisper across time: ancient, eternal, unbreakable. The chorus — "I am the stone, I am the water" — is both a lullaby and a battle cry.

Track 2 · The Conqueror

Bibracte (Julius Caesar)

Written in the first person of Caesar himself, dripping with arrogance. In 58 BC, the Helvetii burned their villages and marched west with 300,000 people. Caesar crushed them at Bibracte and sent the survivors home. The text mirrors the cold, calculated prose of "De Bello Gallico" — history written by the victor.

Track 3 · The Rebel

The Trial of William Tell

An epic two-part drama staged as a trial. Six voices testify: the Judge, the Watchman, Tell's son Walter, his wife Hedwig, a Soldier, and finally Tell himself. Part 1 (82 BPM) is the tense courtroom; Part 2 (120 BPM) explodes with Tell's escape and his unflinching confession in the Hollow Way. The court dissolves. The hat is on the ground.

Track 4 · The Price of War

Blood for Gold (The Mercenary — Marignano 1515)

A father who fought at Marignano warns his son not to follow. The Battle of Marignano in September 1515 killed over 10,000 Swiss mercenaries fighting for a duke they'd never met. The driving 135 BPM groove never lets up — like the relentless march to war. "Blood for gold, son — that's the only trade these foreign kings have sold."

Track 5 · The Peacemaker

The Hermit's Warning (Brother Klaus)

Niklaus von Flüe — farmer, soldier, father of ten — walked away from everything at age fifty to become a hermit in the Ranft gorge. Twenty years later, his single intervention at the Diet of Stans (1481) prevented civil war and held the young Confederation together. The Gregorian choir and sparse Stratocaster create a monastic atmosphere. "Don't stretch the fence too wide," he said.

Track 6 · Brothers Divided

Sword and Bible (Zwingli — Kappel 1531)

Told by a Zürich soldier who shared soup with his brother from Zug at the First Peace of Kappel in 1529 — and fought against him two years later in the Second Battle of Kappel, where Zwingli was killed. A story of how the Reformation tore families apart. The Zuger priest Schönbrunner wept over Zwingli's body: "What a Swiss you could have been."

Track 7 · The Whistleblower

I Wrote It Down (Anna Göldi — Glarus 1782)

Johann Melchior Kubli, the court clerk at Europe's last witch trial, tells how he watched Dr. Tschudi frame his maid Anna Göldi for witchcraft to cover up their affair. Kubli secretly smuggled the trial documents to a German journalist — one of Europe's first acts of whistleblowing. Musically a warm Liedermacher chanson in the tradition of Mani Matter and Reinhard Mey.

Track 8 · The Visionary

No Kings in This Land (Alfred Escher — Zürich 1882)

Alfred Escher built modern Switzerland almost single-handedly: the railways, Credit Suisse, the ETH, the Gotthard Tunnel. They called him "König Alfred." But Switzerland tolerates no kings. He was forced out, not invited to his own tunnel's breakthrough, and died forgotten. The only song on the album without a Stratocaster — instead, an upright piano carries a Gründerzeit shuffle groove.

Track 9 · The Reckoning

Behind These Mountains (The Reduit — Switzerland 1940)

A Swiss woman — not a general, not a politician — reflects on World War II. She heard Guisan's Rütli address on the radio, dug the Anbauschlacht garden, and watched refugees turned away at the border. "A stamp inside a passport like a letter sealed with doom." The mountains protected — but also hid what Switzerland chose not to see. A Glenn Miller Big Band swing with a clear, unflinching female voice.

Track 10 · The Future

The Story Goes On (Quo Vadis — Switzerland Today)

The album's finale brings the story to the present. Zurich hums with tech and AI, neutrality frays, the world demands answers. The bridge looks back across all nine songs — every figure in a single line. Then, as the ABBA-inspired groove fades and the saxophone plays its last note: "And if you want to hear what happens next..." The story goes on.

The Album "The Iron Wheel" (2025 · 2026 Remaster)

A concept album about the cycle of human civilizations. The listener is guided through the eyes of different cultures. The "Iron Wheel" is the common thread — it crushes the old to make way for the new.

Track 1 · Prologue

The Iron Wheel Part 1

The narrator stands outside of time. The wheel begins to turn. A cinematic overture that sets the tone for everything that follows — vast, inevitable, ancient.

Track 2 · Sumer

The First Turn (Cradle of Clay)

The first civilization rises from the mud of Mesopotamia. Cities, laws, writing — humanity's first attempt to hold the wheel in place. It will not hold.

Track 3 · Egypt

Sands of the Afterlife (The Serpent's Kiss)

Egypt's obsession with immortality — pyramids, pharaohs, the Book of the Dead. A civilization that built for eternity and still fell. The serpent always bites.

Track 4 · Rome

The Eagle and the Wolf (Pax Romana)

Rome at its peak: arrogant, brilliant, brutal. The Pax Romana as both achievement and illusion. The eagle soars — until it doesn't.

Track 5 · The Fall · Instrumental

The Long Night (Echoes of the Fall)

An instrumental passage through collapse — the Dark Ages as silence. What falls away when civilization falls? An elegy for everything that was lost between empires.

Track 6 · The Mongols

Empire of the Blue Sky (The Endless Ride)

Genghis Khan and the largest land empire in history. The freedom of the steppe, the terror of the horde, the paradox of a civilization that destroyed civilizations — and preserved them too.

Track 7 · The Inca

Silence on the Andes

Machu Picchu above the clouds. An empire of stone and gold and silence, watching the horizon for something it couldn't name. The ships are coming. The silence will end.

Track 8 · The Ottomans

The Golden Horn (The Eternal State)

Constantinople falls. Istanbul rises. Six centuries of Ottoman power — trade, art, tolerance, and the relentless pressure of modernity. The Bosphorus has seen empires come and go.

Track 9 · Spain

The Sun Never Sets (Plus Ultra)

Spain's golden century: the Americas, the Armada, the Inquisition. "Plus Ultra" — further beyond. An empire that stretched across the world and carried the seeds of its own exhaustion.

Track 10 · Britain

Albion (The Engine of the World)

The British Empire and the Industrial Revolution — the wheel made literal in steel and steam. The engine that changed everything. The cost that changed everything too.

Track 11 · Epilogue

The Iron Wheel Part 2

"We are back here." The wheel has turned again. The narrator returns, looking at the present from outside time. The wheel doesn't stop. It never stops.
