I just got the book / CD / DVD set last week and have enjoyed going through the material. I really liked hearing the songs that accompanied each rhythm. My learning is very visual so having the notation while listening to the CD was quite helpful. It has helped my ear be able to detect and decipher Sega's phrasing on his CDs (Njaga and Wasulun Fenkorow), which was an unexpected bonus. I have yet to check out the DVD, but everything else has been great.
