If you don't know, now you know. Tomorrow night is our DC9 at Night Crawl, which starts at Single Wide around 6:30 p.m., then stops at the Granada for El-P and Killer Mike, who both just released excellent new albums. Then it ends at Beauty Bar for DJ Sober's Big Bang night, and the official after-party. El-P personally co-signed the whole thing, via Twitter, in all caps.

Want a pair of tickets for this magnificent show? Hit us up here and we'll announce a winner tomorrow.
