German composer Volker Bertelmann, better known as Hauschka, is not precious about his piano. Where most kids are taught to treat the the grand instrument like a museum piece, Bertelmann acts like his is a toy chest, filling it with ping pong balls, Tic Tac boxes, paperclips and anything else that will make the sounds he hears in his head. He follows in the footsteps of John Cage (and MacGyver, let’s be real) in his creative approach to prepared piano improvisations, and he recently let NPR in on the process. Even if you’re a fan of his music, these videos are amazing. And if you’re not yet a fan of his music, we recommend picking up his latest record, Foreign Landscapes.
