Useful Exercise for Developing Rhythm Sense

This video was made for some of the folks on the forums but since it's a common struggle for alot of people, thought I might as well make a thread. The idea is to isolate rhtyhm playing into smaller units and practice them independently from one another. This way you can become more free in your rhythm playing and respond to other players in the band better.
