Well, you've got enough on that compilation to tell you that they played in a number of styles and that recommendations would be better linked to the various periods - e.g. if you like the stuff off the first album then clearly the first three Kevin Ayers albums and the first Caravan are going to go down well, if the second then Caravan's If I Could Do It... or Supersister (A Dutch "Canterbury" band) To The Highest Bidder, or even Egg.
Third is just plain classic and though there's nothing quite in its league you should try Wyatt's subsequent group Matching Mole and both Hatfield & The North and National Health.
Fourth is on the way to free jazz (and just not in the same ballpark as Third) and Fifth is mostly unpleasant noise.
Six is more mainstream fusion as is Seven, but both are good if you like a bit of tune.
There's a pile more I could whiffle on about but it'd probably just confuse. So, I recommend you wend your way
over here to Prog Archives, where you can get to listen to a bucnh of MP3s and sort yourself out first hand.
