does anyone know how to join the leigh howard stevens marimba camp in asbury park?

You would want to contact Sue G., at Keyboard Percussion Publications. Call her @ the KPP office and ask for the info. The # is easy to find in one of their ad's but I can't seem to locate it right now. I believe they don't start accepting applications until february or so, so don't worry.
When you do send it in, though, you'll need to send a deposit, a current rep list, a short essay about why you want to attend and two reccomendations (musical and personal) from college professors. Enjoy the seminar, it's one of the most rewarding things a marimbist can be involved in.
