Anthony Burr and Charles Curtis present a collection of curated compositions from Alvin Lucier and Morton Feldman. Two Lucier pieces, "August Moon" and "Trio For Clarinet, Cello & Tuba" are presented here for the first time. Liner notes are excerpted from a lecture on Morton Feldman given by Alvin Lucier. A selection from Alvin Lucier's liner notes: "For Feldman, dynamics serve an acoustical function. When he mitigates a piano attack he reduces that spike of noise that's at the onset of every piano sound leaving only the sinusoidal pure after-sound. It's as if he invented electronic music with the piano."

"Lucier manages to hear a layer of acoustical physics in Feldman's music that perhaps no one else would hear. He's hearing something in Feldman that is actually coming from his own musical world; in a way, hearing his own music in Feldman's, and drawing inspiration from that."
