All professionals and serious students should be eating this up. In just a few minutes of browsing I found a bunch of great stuff:
An interview with Kenny Clarke, and discussion of his career by Norbert Goldberg
Developing Snare Drum Rolls by Sherman Hong
Max Roach's drum solo on Jordu, transcribed by Paul Garretson
Interview with Elvin Jones by Anthony George Bravos
Polyrhythms: Triplets in 4/4 Jazz Time by Peter Donald
...and much, much more— we'll be seeing a whole lot more of them in the future...
