From the recording Cecil Moses & the SGs
This tune was written by the the bass player, Bob Heinemann back when he, Olli, and Marc were still playing with the Vexations. Guitarist, Jason Cameron was talking about that shiver you get when peeing while we were working on this song. So without a title it became the Shiver. Better than Piss Shiver, huh?
And yes, that's a live fad at the end there, not done with any knobs, just dynamics.
