I found this podcast, fascinating, fun, and very inspiring. Master drummer and teacher Michael Carvin shares his vision of teaching and of studying. I highly recommend this program, there are many different kinds of highlights within, and I must say hearing this affected  my teaching!

Michael has taught a lot of great drummers and you can see/hear him all over  the internet, including some burning examples from the early 70s with Freddie Hubbard, but these words are really special. http://www.drummersresource.com/michael-carvin-interview/
