Keller, Max E. (b. March 19, 1947, Aarau). Swiss composer of mostly stage, orchestral, chamber, vocal, piano, and electroacoustic works that have been performed throughout Europe and elsewhere; he is also active as a pianist.
Mr. Keller studied composition with Nicolaus A. Huber, Thomas Kessler, Helmut Lachenmann, and Hans Ulrich Lehmann, as well as German, history and musicology, on a scholarship from the Heinrich-Strobel-Stiftung.
As a pianist, he played free jazz and improvised music from 1966-73, featuring the piano and electric instruments, and has again worked as an improvisational musician since 1985, most notably with Trio Ampio. - composers21.com
