***AVAILABLE AGAIN!!! A totally legit LP-only reissue of this amazing Helsinki monsterpiece from 1970. Shh! documents PEKKA AIRAKSINEN’s experimental compositions, consisting of primitive samples, guitar loop feedback and musique concrete. Sperm also functioned as a wildly theatrical live act à la Dionysius in '69 and arranged underground happenings which occasionally inspired a rallied public outcry against the derisive act of public humping atop a grand piano. 500 pressing.
