I accidentally came across this 3 CD set on Island Records, it's compilation for the years 68 -72. Essentially it sums up the Pink Island years. It comes housed in a CD sized box with each CD in a mini cover and a booklet detailing each of the groups on the set. All the big artists are here, Jethro Tull, Traffic, Free, ELP, King Crimson (with both sides of the Cat Food single, no less) plus Blodwyn Pig, Nick Drake etc. I only played a couple of tracks but the sound is very good. There is even a version of Traffic's Feelin' Alright that was only on a Dave Mason compilation. I ordered it from Amazon UK for about $20. Highly recommended, it really brings back those days of the great Island comp's like Bumpers, El Pea, You Can all Join In etc.
