Jam session.

Wanted: Girls for rock bands. No musical experience necessary. Instruments provided. Misty McElroy claims her Rock 'n' Roll Camp in Portland is the first of its kind for girls only, teaching aspiring rockers ages 8 to 18 the ropes of performing in a real band. Famous female musicians from groups like Indigo Girls and Sleater-Kinney work with the campers, providing instruction, mentoring and, best of all ... free concerts! Weeklong sessions include days filled with music lessons, lunch-time performances, band practice, and workshops on making a 'zine, songwriting, stage presence and more. The first day of camp, girls choose instruments--guitar, bass, keyboards, drums, vocals or electronica--and form their bands. The camp finale is a live concert at Aladdin Theatre, where all the newly formed bands (20 or more) showcase their sounds. The camp started as a project to satisfy Misty's graduation requirements for a Women's Studies degree at Portland State University, and was such a hit that it's now in its fourth year. Sessions run July 19-24 and July 26-31; tuition is $300. No overnight accommodations, but host families are available. Go to girlsrockcamp.org for an app, scholarship form and deadlines.
