Remember that party I went to at the Moma last month? They recorded all the deejay sets! There are 4 - Justin Miller & Jacques Renault, Holy Ghost, T&T, and the Juan Maclean.
Download them here, cover your living room in Twister mats, and re-enact the disco madness.
ps - that pic is the first thing that comes up when you do a Google image search for "disco"
