Look, if you decide to know nothing else about the history of house music, know that there is only one dance music superproducer/remixer/DJ/founding father of true Chicago House Music that goes by the name of Derrick Carter. If you’ve been paying attention all year, you know there is also only one Harlem native fire spitter named Azealia Banks whose special brand of house music/hip-hop fusion has blown up everywhere in 2011.

Via his Soundcloud, Derrick has given us all access to not one but TWO Christmas gifts surrounding said track — first, for just a few more hours you can grab the “212 vs BHQ” version (the one that Derrick himself spins live). If that wasn’t enough, Derrick just posted up with the DJ Bang instrumental version, titled (appropriately) “312″!

“Just the instrumental of my Azealia Banks Rx. Maybe you can use it?” Uh, YESSSSSS? HOUSE MUSIC ALL NIGHT LONG. *** Merry Xmas ***
