Christian Wolff initiated his "Microexercises" series when the Miniaturist Ensemble asked for a piece with no more than 100 notes in it; he went on to create 21 more pieces, 13 of which are performed here by the South African duo of Beat Keller & Reza Khota on electric guitar.

Carl Ludwig Hubsch (tuba); Ole Schmidt (bass clarinet); Chris Weinheimer (bass flute); Robert Schleisiek (piano); and Tom Lorenz (vibraphone) interpret Christian Wolff's composition based on "Union Maid", a song from the 1920's, transforming the work through temporal expansion.

Four composers - John Carisi, Eddie Sauter, Christian Wolff, and Stefan Wolpe - create a program of works with a measured balance in the interrelated and contrasting material.
