Thanks to Christian DeJongh who shared his lessons with Berklee drum professor John Ramsay via the YouTube.com:
I was first exposed myself to Ramsay's teachings via his fine books "Art Blakey's Jazz Messages" and "The Drummer's Complete Vocabulary (as taught by Alan Dawson)".
In particular, Ramsay's book on Art Blakey was a valuable resource for me when it first came out in the mid-90s. Ramsay's experience as Blakey's road manager and sometimes playing alongside him as his "double" drummer translates well in this text and provides a first-hand look at Blakey's style.
John was also very helpful to me personally during my doctoral research, providing some valuable insight into the melodic aspects of Alan Dawson's teachings. Aspects of these are also covered in his book, dealing with Dawson's extensive method and teachings. Highly recommended.
