After the revolutionary In the Court of the Crimson King in 1969 King Crimson did a tour behind the record, which was a hit in the UK and a cult favorite in the U.S. Problem was, by the end, Robert Fripp and Pete Sinfield were the only full-time members left in the group. Fripp was able to talk Greg Lake, Michael Giles and Peter Giles to return to record In the Court of the Crimson King, but the tour would lead to a new lineup. Meanwhile, their second album became their highest charting in the UK, and was a sign of things to come.
