The F. Scott Fitzgerald Theatre (111 Maryland Ave., Rockville; 240-314-8660) hosts the Rockville Concert Band, which is performing classic concert-band pieces (and Broadway tunes) from such composers as Gustav Holst, John Philip Sousa, and Karl King.

If you’re going to sweat anyway, might as well do it boogie-style with music from Endless Boogie at the Black Cat. The four-member group, based in New York City, is known for its endless, soulful grooves. $10; 9 PM.
