I heard Pao isn't Sound's drummer anymore..
one underrated drummer for me is Ed Shaughnessy..big band drummer..who's played with Count Basie, Duke Ellington and Doc Severinsen's band...
how about Bill Stewart. I think his famous, but imo, not famous enough..he has touch of his own..the way he produces good tone from his kit..
Will Kennedy who used to be with the Yellowjackets...tigas nga lang tignan..but like Bill has got good tone. He grooves so well too. He's not flashy, but he sure still plays pretty much in the pocket.
