yes he is indeed 
there are loads of useful videos of amazing drummers at www.drummerworld.com if cutting up breaks is your thing.
hahaa, good to see him i action. I remember listening to a 45 minute drum solo spread across 2 sides of a vinyl with him vs Louis Belson - this blew me away too, and so I recorded it, and although completely unsampleable, it was quite an ear-opener when I was younger, and exhausting just to listen to it.
On a bit of a sideline - there’s this cool 5 part documentary with JoJo mayer & his band whos’ pretty impressive imo. Starts with a nice intro about the Amen…
