Originally released in 2005, Peristalsis marked Ramp's first full-length release. Since then, this album has largely been unavailable and is just being republished for download now.
The fourteen tracks on this album span a variety of styles but primarily focus on experimental electronic industrial and ambient sounds. Aiming for a rich, lush feel without becoming pointlessly complex, this album serves as a counterpoint to growing electronic minimalism. While it is largely instrumental, aside from one track with a sampled spoken-word performance, vocal textures underpin quite a few of the sounds.
