http://www.youtube.com/watch?v=ZSxQR7rbKSEWorth listening to if you haven't heard it before, a bit of a curate's egg like a lot of their stuff, but definitely the best surviving recording of Woolly's playing. Galadriel, She Said and Mocking Bird are the stand out tracks as far as the tron is concerned, personally I would skip "Summer Soldier."
I don't find Woolly's mellotron playing as interesting in the later BJH and Maestoso albums although I would consider "One drop in a dry world" his finest work overall.
