Superb online instruction at a fantastic price
Look, I've been using this for a couple of weeks now and already my playing has vastly improved along with my knowledge of theory. If you're serious about drumming as a hobby or as a future career I'd say its well worth it. The amount of online content available is superb not to mention all of the freely available online content as well.
So like I say, if you're serious, give it a whirl!!
