I came up with this one while working on linear patterns, and listening to a lot of James Brown. Try it as both straight 16ths, and as "swung/ pseudo hip-hop"" by using 16th-note triplets as the underlying subdivision. After you get them down,  you can start working on your own variations. Send them in , and I'll post them for others to check out!!

Here's one that's fairly common now, but back in the early 90's, it was killer!! Try the basic one, and then some of the variations a la Steve Rucker at "The U"!!

This is an inverted dbl. stroke roll between the BD and SD. This flows nicely at a lot of tempos. At slower tempos it has a nice, broken quarter note, triplet feel. At faster ones, it just flows and rolls right along.

Here's a warm-up designed to work intricate drags and accented rebound strokes in both hands. Start slow and build up tempo!! 

Here are  some ideas and concepts that I've either had some success with on the gig, or I found to be helpful in developing a specific technique. Enjoy!!
