How would you like your piano prepared this evening? As Hauschka, Dusseldorf’s Volker Bertelmann augments a standard acoustic keyboard with ping-pong balls, strings, wood, foil, paper, and other objects. He’s a one-man band who often sounds like a complete ensemble, especially when augmented by electronics. The happy, dark, and intermittently house-hoppy tracks on his new Abandoned City force you to hear an old instrument in a new way.
