Dark Side of the Moon A Cappella Vocamotion CDI do have this on vinyl, but today's listening was on the train so it had to be a CD Rip on my iPod.This album is really well done. Everysingle sound from the first note to the last was produced by a human voice, including all of the drums and sound effects.
