David Morales helps Boom Boom Room celebrate tonight at Green Dolphin.

Boom Boom Room
10 p.m. at Green Dolphin Street; $10
The venerable house-music event celebrates its 19th birthday with a special installment featuring DJs David Morales and Hector Romero, in addition to residents, Diz, Uncle Milty, Just Joey and Michael Serafini. RSVP to rsvp@boomboomroomchicago.com.

Policeman's Log
9:30 p.m. at Gorilla Tango Theatre; $10
There are two sides to every story, but only one version of the truth. Pulling actual police reports from recent newspapers, the cast of "Policeman's Log" will show audiences how the incidents 'actually' happened. This fully improvised show will shine a new light on those who break the law, and those who uphold it. Tonight's performance is the final one in the run.

Get It Together Again
8 a.m.-7 p.m. at Chicago Tourism Center Gallery, 72 E. Randolph; free
This exhibition of work by local, national and international artists is organized by Chad Kouri of the Post Family and Ed Marszewki of Co-Prosperity Sphere. It includes over 25 works on paper, mixed media and installations like Adrianne Goodrich's grocery store shelves with hand-drawn products (pictured). Guests can create their own collages with provided materials (or you can bring your own).
