The melodic and, in the case of the solo piano music, timbral materials from which Christian Wolff's (b 1934) music is made are rarely unusual; these are ordinary, everyday things. However, Wolff's rhythmic invention is of great range and variety: complex polyrhythms, speech-like-rhythms, the music flowing at a freely fluctuating rate or proceeding in a plain, straightforward manner, silences. This mix of unusual and ordinary results in a music unlike any other. And, in a piece of such length as Long Piano, the ongoing appearance and accumulation of a great number and variety of short passages results in the constant renewing and refreshing of the listener's perception. This is the world-premiere recording of the composer's largest solo keyboard work to date.
