Chicago-born DJ/production duo and superstars of the burgeoning trap-music scene Flosstradamus are busy guys. Last week they packed the cavernous Terminal 5 in NYC. This week they took part in an energetic Reddit AMA and released a new single, “Mosh Pit,” featuring Atlanta MC (and Future buddy) Casino (whose Ex Drug Dealer mixtape is one of the more sadly overlooked rap releases of 2013), that’s the first track to surface from the pair’s monthlong stay in ATL earlier this year. And the rest of their December plans look something like this.

At the end of the month the two will be back in Chicago to close out the year with their biggest headlining gigs in their hometown to date: two nights at the Riviera over New Year’s. They’ll be offering a preview of what to expect tonight when they stream their set live from the 9:30 Club in Washington, D.C. The show starts at 11:30 central, and probably beats trying to actually do something IRL when it’s so stupid cold out.
