The Central Florida Community Band, a sub-organization of the Orlando VFW, has been performing for over 25 years for veterans and the Central Florida community. They perform between 12 and 15 concerts each year and perform for events like the Memorial Day Ceremony, the Veteran's Day Parade, Christmas concerts, and other community events. They're always looking for new members to join--you don't have to be a veteran and there's no audition or fee required to join.
Check out their website to see the schedule of upcoming events and concerts and to find further audition information. Follow their Facebook page for updates as well.
