That's A Groove Vol. 1, the first book from Richard Millsap, is a drum set transcription book featuring songs performed by some of the leading voices on the instrument in the 1960s and 70s; from Hal Blaine and Jim Gordon to James Gadson and Levon Helm. This book was designed to inspire the reader to go deeper into the material, with a focus on information about the writing/recording of the songs, the grooves, and the drummers who gave us these iconic performances.
