Tepfer earned global acclaim for his 2011 release Goldberg Variations / Variations, a disc that sees him performing J.S. Bach’s masterpiece as well as improvising upon it—to “elegant, thoughtful and thrilling� effect (New York magazine). Tepfer’s 2019 video album Natural Machines stands as one of his most ingeniously forward-minded yet, finding him exploring in real time the intersection between science and art, coding and improvisation, digital algorithms and the rhythms of the heart. The New York Times has called him “a deeply rational improviser drawn to the unknown.� His 2023 return to Bach, Inventions / Reinventions, an exploration of the narrative processes behind Bach’s beloved Inventions, became a best-seller, spending two weeks in the #1 spot on the Billboard Classical Charts.
