Here are some clips of Dave that I got at Sabian Live in January. The one linked here
is the longest at over four minutes, and there are links on the page to three other clips as well. This one is the best, though, with some very nice grooves, a tight solo, and a jamming finale. There is simply no way to watch this guy play live and not appreciate both his technical ability and his feel for the groove. He is an amazingly well rounded drummer.
