King Crimson "Cat Food / Groon" EP/Single 1970

In the Wake of Poseidon.The album was re-released in 2010 with a near-complete new stereo mix by Steven Wilson and Robert Fripp as part of the 40th Anniversary release sequence. As tape for one track, "The Devil's Triangle", could not be located, the original stereo was included instead. The CD also includes a new mix of "Groon" ("Cat Food"'s B-side), an alternate take of "Peace – An End", and Greg Lake's guide vocal take of "Cadence and Cascade".

The DVD-A features a 5.1 mix by Steven Wilson, with "The Devil's Triangle" up-mixed to 5.1 by Simon Heyworth, hi-res stereo versions of the 30th anniversary stereo master, the 2010 album mixes and ten hi-res bonus tracks including the original single "Cat Food"/"Groon", the bonus tracks from the CD, and a number of other session takes, rehearsals and mixes
