My 2 girls have been going here for the past year and love it. The school, founded by Steve Smith has been around for "I think" 15 years and its sort of a makeshift "School of Rock".
While its environment is what some might say casual.. that is an understatement :)
The teachers are great and the fact that a lot of talent surrounds the business is obvious. Death Cab for Cuties drummer used to teach here... not too long ago.
The business doubles as both a studio and a rehearsal space so they frequently have all ages shows where the artists can display their talents.
The name is a little misleading as while the do specialize in drum lessons they also offer training in many other instruments and offer summer programs/camps for kids.
