Gymnosphere: Song of the Rose - Music for the Well-Tuned Piano

A student of Terry Riley, the Californian avant-garde composer delivers an awe-inspiring, massively reverberating double-album of solo piano improvisations. The recording heavily relies on just intonation tuning and was famously played back and re-recorded within the cavernous acoustic environment of Grace Cathedral in San Francisco. The resulting sound is a cascading, deeply meditative blur of overtone-rich minimalism.
