This is the first album playable at any speed. Being all-instrumental music, there are no voices to affect the realism of the orchestrations. Thus the album becomes a collection of electronic concertos, each movement being defined by the speed of the turntable. A turntable with speeds of 33, 45 and 78 rpm, creates a different ratio within the pieces, yet maintains a familiar melodic drama.
Saying all this, the record was recorded to produce the sound you hear at 45rpm and any compilations using tracks taken from this record reflect this.
Deliberately playing or recording records at a higher speed gave an antic quirkiness to voices; doing so at a slower speed changed music and voice to an ominous, growling tone. Nash the Slash took advantage of this speed/tonal effect with his 1981 12-inch disc Decomposing, which featured four instrumental tracks that were engineered to play at any speed (with the playing times listed for 33⅓, 45 and 78 rpm playback).
Here we present 16 rpm speeds and 45 rpm speeds. For an even weirder effect, you can play 2 of the tracks at the same time.
