Masturbatorium was the soundtrack for a performance art/goddess ritual by Annie Sprinkle, and between the title and its provenance, one naturally tends to view the piece in the context of a sexual act. The piece itself begins quietly enough, with a repeated piano figure over which various other drones, resonant frequencies of the Earth, and repeated electronic figures are layered. In the performance, this section was a time of preparation and evocation. After about seven minutes, this repeated figure gives way to a quiet, low, crunchy rumble, to which a short vocal sample is added after a few minutes. Almost all of the sounds in the second section are constructed from Sprinkle's sexual activity. The last four minutes are comprised of a tantric techno rhythm from the Anti Group, with vocal samples from Sprinkle having her first "Breath Orgasm," increasing in speed and pitch, suddenly stopping just before the close to leave quiet, breathy drones to fade out. This release is the first part of a projected trilogy based on sexual energy, and is intended as a practical and functional work which will duplicate the energies of the performance ritual outside the performance space.
