>>It’s a dark, dark Monday night at the Black Cat as three goth-leaning punk bands are in town.

Tuesday

>>While their days as boys a distant memory, the men of Boyz II Men, the biggest selling R&B group in history, have still not come to the end of their road.

>>Coolooloosh, an Israeli band that plays hip hop, jazz, reggae & funk w/ English & Hebrew lyrics, will be at the Kennedy Center Millennium Stage. Free, 6 p.m.
