Commissioned by Mabou Mines, the experimental theater group from New York, for their interpretation of "King Lear," Oliveros' Crone Music is a subtle and haunting electronic music endeavor. Interfacing an abundance of digital delay processors, reverb effects and foot pedals to bend pitches from piercing to twisted, sonorous tones, with her one-of-a-kind expanded accordion, Oliveros produces rich, eerie textures.
