It's a holy grail for all my breakbeat-related needs. I'm not a drummer, but I'm finger drumming on Maschine, as well as producing music on Polyend Tracker with heavy breakbeat usage. This book not only taught me different patterns and ways to apply it, but introduced me to the history of breakbeats and important people in it. It's just fun to read! Also the author is great guy, he is running a youtube channel where he teaches making beats. I can definitely recommend this book for anyone who is interested in the subject.
