In the late 1970s Morton Feldman established an ensemble, Morton Feldman and Soloists, at the university in Buffalo, New York, where he taught. Feldman was one of its pianists, and the group's repertoire naturally included a number of his own works, but it also ranged from Satie to Xenakis, Kurt Schwitters to Toru Takemitsu. Crippled Symmetry, first performed in 1983, four years before his death, was one of the pieces Feldman composed specifically for members of his own group, the flautist Eberhard Blum, pianist Nils Vigeland and percussionist Jan Williams.
