I've changed my mind somewhat on OP. I don't really like a lot of the trio with bass and guitar material, I think a drummer gives me more to be interested in and helps OP somewhat to be a bit sparer. As I said above the London House box, which I got rather cheaply on ebay along with some other members, helped prod me further into his camp, though listening to his work as an accompanist/musical director (?) for Granz helped me on my way (he occasionally put down some brilliant solos on those records, and his general organization and the cohesion he helped foster in his section mates helped a lot of sessions to gel). I think if you get deeper into his music some of these excesses appear eventually to be less about flash and drama and more about fleet thinking and trying to get more in there than others may . . . . Anyway, I can't listen the man all day, but I can enjoy his music, in solo and trio (with bass and drums) formats the most. . . .
I don't really think it matters TO ME why Monk or Miles or any number of other "greats" disliked him. . . . In many cases there are going to be extramusical reasons (I find that often to be the case with Miles!)
