Robert Fripp, Trey Gunn, Bill Rieflin: The Repercussions of Angelic Behavior (2007)
Freely improvised ambient metallic and electric skronk/jazz/rock. One moment they're chewing into your brain like robotic earwigs on a mission, the next blissfully floating away on clouds of hallucinogenic pepper spray.
