The Red Room is a student-run all-ages (in other words, alcohol-free) live-music club inside a Berklee College of Music coffeehouse. It might be the best deal in town if you want to be able—eventually—to say that you saw the senior recital of a breakout star. The 200-capacity venue has top-notch acoustics and books professionals as well as students. To buy advance tickets without a service fee, or to use your student discount, visit the Berklee Performance Center box office at 136 Massachusetts Ave. Closed Sunday; coffeehouse closed Saturday except during shows.
