Abdou Kounta, one of my most important and influential djembe teachers, taught at Lisangua ya Bato, a Dance and Drum Camp held annually for over 15 years, in the heart of New York's Catskills.
Mathieu Charrois is from Montréal, QC. He's been playing since 2004, and has picked up a lot of solo phrases from Mamady Keita and other djembefola... His lessons are fantastically explicit, with audio mp3s, notation, and detailed explanation. Wonderful resource!
