Hod O'Brien has always been this mysterious figure to me. Showed up on a couple of good 50's albums (Three Trumpets, the Rene Thomas album), then again on Roswell Rudd's fascinating 'Flexible Flyer' with Sheila Jordan in the 70's, then fell off my radar. I see a bunch of later albums by him that I've never heard. Just read his wikipedia entry, and he looks to have had substantial connections in the early 60's, but seems to have been unrecorded in that period. I like his work on the Rudd album quite a bit. Also, would not have expected him to have co-led a group with Cameron Brown and Beaver Harris (think more of that being, say, Dave Burrell territory). Looks like he played with people from Sonny Greer to Archie Shepp. What else do I need to know about him?
