This book is a goldmine of information and ideas pertaining to the addition of the salsa feel in your playing. The authors lay out, in both English and Spanish, the different latin styles and feels clearly, and the included cd's make learning the material that much easier. The different patterns discussed include the clave, tumbao, songo, guaguanco, cha-cha, mozambique, and afro-cuban styles. Also included are 6 songs (complete with charts) for the student to play with (recorded with and without drum/bass tracks). This book is a must have for a player of any level. It was recommended to me by a bass player friend of mine who plays in a touring group specializing in latin/flaminco music. It has made a huge difference in my playing, and I've been drumming for 23 years. Get this book and enjoy the new world of ideas and possibilities!
