Yes! The Summer Blast-off, which features the Marine Corps Band and a spectacular fireworks show, generally occurs the Sunday of Memorial Day weekend.

In addition, artists appear at Pre-Performance Discussions prior to some performances (about 10 each summer), and these are free of charge. What type of sound console is used in the Filene Center?
