The night before SXSW Music kicked off, SXSW Interactive was ending. The fine folks at the AV Club and The Onion celebrated the meshing of the two conventions with a pretty stacked bill: new indie favorites Mothers and Beach Slang closed out the gig, but the most memorable was definitely Open Mike Eagle. The Chicago rapper's performance bordered on comedy—he spit lines about burritos and hangovers, splitting his pants like Lenny Kravitz and one moment even offered advice to a lonely attendee (it was effectively, "be this man's friend," but still. Powerful!) Near the end of his set, comedian Hannibal Buress hopped on stage, rapping from beneath some seriously cool '60s shade. If there was ever a time to watch a concert space full of start-up wizards losing their cool over hilarious hip-hop, it was then.
