Don't let the title fool you into thinking this is a specialty book for funk or even for just rhythm. There is an emphasis on funk, but the examples/exercises are excellent technique builders across genres. Also, since the rhythms are often complex, they can be judiciously incorporated into solos (a la Hendrix). This book would be frustrating for most beginners, but for anyone who wants to break out of basic 4/4 strumming and make their rhythm playing count (sorry for the pun), this will be a great investment.
