I try my best not to be a "re-blogger", but I was over at Cruise Ship Drummer! the other day and saw that Todd posted about a Steve Gadd book that is now available as PDF for free, so I figured it would be irresponsible not tell you about it.
This is a very cool book by Danish drummer, Hans Fagt, that features some of Gadd's best stuff. And, to be honest, there were a couple of recordings in here that I was unfamiliar with and got to discover for the first time.
The format is great as well. Rather than multiple page layouts of whole tune transcriptions, Fagt has broken everything down and gives us the main grooves of each tune and a handful of fills.
It was originally published in 1985 and apparently has been out of print for awhile. Hans is now giving it away if you simply sign up to his mailing list. As he is so kindly handing it out essentially for free you should do him the courtesy of actually signing up to the mailing list to get it rather than just sharing the PDF.
