Full-length collaboration from Duane Pitre & Eleh! The electronics, from which both pieces are constructed, are tuned using pure intonation that utilizes the prime numbers: 1-3-5-7. Additionally, PITRELEH utilizes the septimal kleisma to create a disturbance with the seventh harmonic. This, in turn, creates mathematically based, naturally occurring rhythms. Tuning by Duane Pitre.
