Zoro did a clinic out here a year or two ago. I really dig his stuff, he is a veteran, and survived the drum machine era, as a working drummer by being able to play the stuff live, that people were sequencing (huge props for that).
I've got the Hip Hop Era video, and it's pretty cool. I thumbed through the book it seems like it is a little more focused on being a documentary on the history and the originators of certain feels, and roots of some of the rythms, but it's got some exercises too. I plan to get the Funk video at some point.
He's got some pretty killer licks live, but he really emphizes playing the groove, and being in the right place on the beat as the main focus (important stuff).
I'd say there is something in the series for everyone. If you are looking for fancy stuff, this is probably not what you want, but if you want more insight on different feels and grooves of the styles he covers, you'll definitly get something from him.
