New York-based composer, pianist, and coder Dan Tepfer, who has previously improvised a companion to the J.S. Bach's Goldberg Variations, has returned to using the animating idea in music by Bach as a starting point for his riffing, on his latest album, called Inventions/Reinventions. On this record, Tepfer takes Bach's 15 Two-Part Inventions as written (which he describes as “something deep happening under this simple surface”), and taps into what J.S. Bach was most famous for – his improvising genius, but in music that sounds like Dan Tepfer, in the remaining 9 keys of the complete cycle.

Tepfer feels that the idea of joy is omnipresent in Bach’s music, and in his own play as he riffs on Bach, he finds a visceral joy in creation. In doing so, Tepfer tells his own story - his love of Bach from childhood, his appreciation of Brazilian music, his admiration of Lee Konitz, - and not only improvises within a framework, but also creates an entirely new structure for the frame. He also sings what he plays to make sure that he means it, which brings to mind another improviser, American jazz pianist Keith Jarrett. Dan Tepfer performs both J.S. Bach’s Two-Part Inventions, and his own unique reinventions, in-studio. - Caryn Havlik
