Some friends of ours are doing a show at 
Helios (411 Westheimer @ Taft) tonight. Check it out:
Secret Beat Society presents the NEW BEATNIK REVUE - Poetry and hip-hop deep fried and spiced with the flavor of the south. Hosted by Lyric Osiris with DJ MR.E.
This week the Secret Beat Society will feature a perfomance by The Last Soul Descendents (acid jazz, hip-hop, dub, drum-n-bass). Starts at 11pm. $3 cover.
Drop Trio has yet to do a show at Helios (not sure why!) but it's a great venue for checking out Houston's best new jazz, groove, hip hop, etc. There is always great stuff going on there, and tonight is no exception. 
The Last Soul Descendents have some of the most creative and deep downtempo / dub beats, and the most beautiful singing. You can always catch Darren & Leah, the core of the group; and if you're lucky, you can also hear Dionne Banks and Diva Karina.
The Secret Beat Society is fantastic - an interdisciplinary neo-beat collective, part poetry and part music, with poets and musicians spanning a spectrum of styles - classical to slam - hip-hop to jazz. Conspirators include Mike McGuire, Kool B, Lyric, and Ragah El ... definitely some of the coolest stuff going on in Houston these days, so go check it out!
