I've been exchanging email with the folks at Louisiana Folk Roots and here is the lineup of accordion instructors for the Dewey Balfa camp in April.
Beginning: Kristi Guillory
Intermediate: Dirk Powell
Advanced: Ray Abshire
Creole/zydeco: Corey "Lil' Pop" Ledet
Todd Mouton from Folk Roots passed along info. that the camp is about full, at least as far as cabin and dorm spaces are concerned. Plenty of camp sites available at Chicot State Park (where the camp is held). Keep your eye on the web site as it should be updated soon.
