Trans Cover Express

In the great pantheon of music, certain names resonate beyond epochs and genres: Bach, Nirvana, Mozart, Ravel, Radiohead, Vivaldi, Bashung… So many singular, intense universes, sometimes at opposite ends of the spectrum, but carried by the same force: that of raw emotion, the quest for beauty and sonic exploration.

What if these worlds came together? What if we dared to bring them into dialogue beyond styles, labels and habits?

This is the audacious challenge taken up by Trans Cover Express, a project born in Limoges in 2025, the cradle of a thousand-year-old musical tradition profoundly free, between the troubadours of yesterday and the creators of today.

Conceived by musician and composer Nicolas Repac, a singular figure on the French music scene (notably with Arthur H, Mamani Keita and his own solo project), Trans Cover Express is a variable-geometry line-up, bringing together artists from a wide variety of backgrounds: classical music, rock, chanson, world music, electro…

But here, there’s no question of simple repeats. Each work is transformed, like an inspired rewrite. Mozart becomes organic, Nirvana becomes lyrical, Vivaldi is reinvented in tribal pulsations, and the Doors take on baroque accents. You don’t immediately recognize the tracks, and that’s all to the good: you rediscover them in a new light, between nostalgia and surprise.

The arrangements blend the vibrant strings of violin and cello with the raw energy of electric guitar, organic drums and electro-acoustic textures. Each piece is conceived as a sound painting, a moving landscape, an inner journey.

At the heart of this sonic journey:

  • Nicolas Repac, on electric guitar, a discreet but magnetic conductor, sculpts the sound with rare finesse. His playing, nourished by jazz, blues and electronic experimentation, gives color to the ensemble.
  • Mirabelle Gilis, a luminous violinist, crosses paths with classical music, Celtic music and chanson. She infuses lyricism and energy into every musical phrase.
  • Olivier Koundouno, a demanding and adventurous cellist, moves from contemporary repertoire to improvisation with ease. His cello is a voice in its own right, by turns grave, tender and volcanic.
  • Patrick Goraguer, a precise and inventive drummer, weaves rhythms with a rare elegance, between rock pulse, jazzy groove and orchestral delicacy.
  • Ludovic Joyeux, with his electro-acoustic sounds and treatments, works like a painter of textures. He enriches sound space, adding breath, mystery and depth.

Trans Cover Express is a collective adventure, a manifesto for liberated, transgender, living music. A concert like a moving train, taking the audience from one era to another, from one continent to another, from one emotion to another.

Here, everything is transformed, elevated and embraced. A bridge between worlds. An experience to live.
