Sub Rosa are releasing a compilation of previously unreleased tracks by Frank Zappa's keyboard player Don Preston, who made Robert Moog say "That's impossible. You can't do that on a Moog" of his "Waka/Jawaka" solo.
Preston played with Zappa and The Mothers Of Invention from 1966 to 1974, and became close friends with Robert Moog in 1969. This nine track album, titled Filters, Oscillators & Envelopes 1967–82 includes a collection of tracks made on the instrument Preston developed himself, a home made synthesizer with a series of oscillators and filters. It includes Preston's first piece made on this instrument, titled Electronic Music from 1967.
The compilation will be released on CD and LP, with the first 150 records available on marbled white vinyl. More details here.
