Between formed in Munich around two classically trained musicians—minimalist maestro Peter Michael Hamel and Popul Voh oboist/inventor Robert Eliscu—and Roberto C. Détrée, an Argentine bossa nova guitarist. Taking in a future superflautist and two African-American jazz percussionists, Between forged from their diverse musical backgrounds a strange beast. Relying on classical Western instruments, they created avant-garde improvisational music with a wholly Eastern sensibility. They used distorted piano and organ instead of synthesizers and Eliscu's robotic single-stringed motocello to make acoustic kosmische hum. These first two albums have grown on me quite a bit over the years, particularly And the Waters Opened. I also recommend Dharana (1974), a worthy follow-up, if a bit too soaring and majestic at times for my taste.
