I really think MF should have won some kind of award for Live from San Fran. The whole album rocks, but especially the solo section on South 21st St. Shuffle. I don't know which trumpet player it was, but going into the solo section he does this killer shake and it's all on after that, a battle of the horns between the trombone (Steve?) and Maynard. Of all his albums, that one is, to me, the most successful synthesis of Maynard bringing his vast knowledge, talent, and experience to a modern audience.
