COCEK! BRASS BAND Inspired by a library discovery of the music of legendary Romanian ensemble Fanfare Ciocarlia, this Boston-based five-piece outfit runs leaner than your typical brass band and mix their Balkan with reggae, klezmer, Dixieland and marching band, and much else. They’ve just released their debut record, “Here Comes Shlomo.” Dec. 10, 9 p.m. Tickets: $10. Middlesex Lounge, Cambridge. 617-868-6839. www.middlesexlounge.us
