I have three of his instructional book/CD combinations.
- "Solotechniken für Handtrommler" This comes with two CDs, one for 4/4 and one for 6/8 rhythms. Not really rhythms on these, but drills you can pracice. Various patterns and rolls that can be incorporarted into solos. Basically, drills to make you stronger rhythmically.
- "Djemberhythmen Aus Mali" Also comes with two CDs. Recorded with Drissa Kone, this is an instructional book for various rhythms. Drissa plays nice solos at a speed that allows you to learn them.
- "Westafrikanische Djembe Rhythmen" Instructional CD for a bunch of rhythms and another performance CD with the same rhythms.
All three are high-quality teaching material. I haven't fully explored them yet, but they are definitely among the better publications of their kind.
Cheers,
Michi.
