Im not so much concerned with the history as I am in just knowing the variations, and being able to recognize which patterns I can play when it comes up in a song. I'm reading the book so I get a full understanding of what she's talking about, but I must say Im disappointed so far. I will state that my disappointment stems from comparing it to another book though. Before buying this book, I purchased the Latin Bass book by Chuck Sher and Oscar Stagnaro to learn latin bass lines that I could play on the piano. His format was very simple; just read the transcriptions while listening to the recordings at the same time, and eventually you'll get the hang of playing the lines. His CD crushes this one in content, application, length, and quality. Its a real recording of himself or another person playing the transcribed pattern with a real rhythm section. Since its live, you hear a lot of the variations right in that one track, as compared to the Montunos book that includes a "Play Along CD" that only really sounds for 20 seconds! By the time you start playing, the track is over. The CD further frustrated me because they used midi sounds instead of a real keyboard or piano. Lastly, I started to get the feeling that each pattern was separated onto its own track to just give the feeling that you have a lot. I heard patterns repeated, and pretty much every pattern was repeated on a subsequent track to show a variation of playing it in arpeggios. For example the pattern for playing the song, "Oye Como Va" is played on one track then repeated on another in a different key. Thats crap! She could have done that on one track, live, and played lots of variations right there, and had the transcriptions of the patterns so we can follow along. The only time a pattern should be played on another track is if the clave changed.
Btw, the montuno patterns the piano player uses on the Latin Bass Book are amazing compared to these. The CD is the bomb. I could listen to it even if I weren't trying to learn it. I wish there were transcriptions for the piano, but its just for bass. For the piano player who doesnt mind transcribing montunos by ear, The Latin Bass Book is a much better bet. And you can pan the piano side!!
