If you're going to drink this Saturday, make it for a good cause! El Rio is hosting the Connecting Worlds benefit from 4-7 p.m. Jam band Chemystry Set will be playing, there's going to be photography exhibits, and all the money raised (sliding scale at the door) will go to the groups Afghans4Tomorrow (which focuses on rebuilding Afghanistan) and First Exposures (a local photography/mentoring group for students).
