What to do this weekend — our suggestions

1. Get to know a man-eating plant. Friday night at 9 p.m., there’s a free, outdoor screening of the Little Shop of Horrors at 9 p.m. at City Market.

2. Hot it up. Starting Friday night at 8 p.m., Summer Salsa Fever at Harrah’s VooDoo Lounge features some heavy hitters from the world of salsa music.

3. Reflect upon the art, life and legacy of wacky author William S. Burroughs. An exhibition of his artwork opens for one night only Saturday at Lawrence’s DotDotDot Art Space. Another Burroughs-centric show opens Sunday at the Bourgeois Pig.

4. Check out some roller derby action. The KC Roller Warriors get brutal starting at 7 p.m. Saturday at Hale Arena.

5. Support Susan G. Komen for the Cure and rock out to Softee and others at Mammapalooza Saturday night at Crossroads Live behind Grinders. The show starts at 7 p.m. and a whopping 100 percent of ticket sales go to the charity to fight breast cancer.
