Prog bands are notorious for shuffling their lineups more often Major League Baseball teams, and King Crimson are no exception. The prog pioneers had only been around for five years by the time they cut Red in 1974, but most of the original lineup was long gone. Only leader Robert Fripp remained; by this point he had recruited former Yes drummer Bill Bruford and future ASIA lead singer John Wetton. (Side note: Bruford has the unique distinction of being the only man to serve time in the holy prog trinity of Yes, King Crimson and Genesis.) The group cut Red knowing it would be their final album before they split up, and they really gave it their all. Many fans point to it as their best work, and even non-prog junkies like the late Kurt Cobain have offered it effusive praise. Good lucking finding it on iTunes or Spofity, though. The group has some beef with the business model of online music.
