Probably the most direct route would be to send a PM(message under "My Stuff" heading)to Jc(Jean-Claude Benoit), who's now in charge of the audition list. You should be aware that many of the listings aren't up-to-date and may no longer be available for an audition. In any case, you can ask if there are any other possibilities in your area.

Enjoy the music, not the equipment.
