 "Song Cycle" contained experimental production and recording methods, including varispeed and regenerated tape delay.Audio engineer Bruce Botnick is credited for inventing the "Farkle" effect, an ingenious modification to a Sunset Sound Recorders echo box.The Farkle effect was used most prominently on violins, harps, and the intro to "The All Golden", and involved very thin splicing tape folded like a fan attached to a tape overhead.
