I saw the latest (and probably final) incarnation of King Crimson the other night and I still can't get my jaw off the floor.
They played lots of old material that they haven't done in years, such as "Lark's Tongues in Aspic, Part I" with sax taking the violin parts and "The Sailor's Tale" with Robert Fripp's trademark banjo-style solo. I could go on …
But what would probably be of most interest on this site is that they used three drummers set up at stage front: Pat Mastelotto, Gavin Harrison (out-of-this world solo during "21st Century Schizoid Man"), and Bill Rieflin (former REM sideman who also played mellotron). I was pretty skeptical about this going in, but they totally made it work.
The tour is almost over—there'e one show left in San Francisco and another in Seattle—but it's definitely worth a look.
