Made with Xara Marvin Ridge Band Booster Membership Band Booster Membership is a vital part of our band program at Marvin Ridge. MRBB is a parent organization that supports all band activities. All parents of our band members are invited to participate in the Band Booster activities and to attend the Band Booster meetings. Membership allows you a vote at our general meetings. Your annual fee of $50 helps to fund the numerous expenditures that a program of the nature encounters. We thank you in advance for taking an interest in our program and welcome you to MRBB. Please fill out our membership form           (click here) and place it and payment in either of the band boosters boxes located in each of the band rooms.
