Two productions from the electronic studio of the Swedish Radio, Stockholm. Originally created in 1967. The second track is the same as the first, but played at half-speed, which is in effect one octave lower. The first track was originally released in 1970 on LP by Wergo under the name "Was??".
On IMPREC label sticker affixed to the shrink wrap: "[...] Initially reissued by Jim O'Rourke on his Dexter's Cigar label in 1997 and now available on Important with expanded packaging. Amplified infinity."
