For live performances, they could sit on toilets. On a serious note, the piece "For Stefan Wolpe" is really nice. The MODE releases "Composing By Numbers" and "The Indeterminate Music" are my two favorites for intense listening, or just relaxing. Feldman went through an indeterminate phase of composing, and later through-composed every note.

Feldman's String Quartet No. 2 is available from MODE as a regular CD, or as a high-res DVD audio disc. This quartet clocks in at over six hours. The story goes that the performers considered using catheters before the session, but instead opted to limit their fluid intake before the recording.
