I am posting the sound files to a now out of print and very hard to find music education book . It is the music education book; Güemilere: Guide For Afro-Cuban Percussion by Regino Jimenez/ Scott Wardinsky, which I can only find the barest of information on, but the sound files are an excellent educational resource. They approach the rhythms by adding each instrument one at a time, building it, so the student can hear the parts and how they go together. It is a very original approach.

(I'm using a free rapdishare account so the downloads will have to be uploaded periodically. Please make requests for re-uploads in the comments. Link last updated 12/13/10 as mp3 files)
Scott Wardinsky is still active, sadly Regino Jimenez is no longer with us, however his music is still available on Descarga.com. You can honor both of these musicians and educators by studying their work and learning to play these rhythms.
