I studied wih Doug for a while. He is the consummate sideman. Played with a million people but hard to find him on records. Al of course is great. Also check out his stuff with Kevin Hays and Bill Stewart. He is a real nice cat and a great teacher. When the other guys were making me sweat through Simandl, he was the one that had me transcribing PC and trying to play simple but powerful stuff, lines in 2, a la Israel Crosby.
