Re: Books, DVDs, or Online?
My 2 cents...There is nothing wrong/negative with any method of learning, so long as the material is well-researched and understood by the person presenting it. I could put an educational drumming video on YouTube, and, unless it was a lesson on what not to emulate, it would be terrible.
#1. There are classic methods of learning, in books, that really can't be beat IMO.
#2. Support an artist, pick up their material, you'll learn something...or enjoy yourself at the very least.
There are many many good resources on the internet too! Good for all :)
Practice, Improve, Repeat...
