Who else—besides maybe early Girl Talk—can do mashups like Kap Slap? The DJ has long claimed he makes music for raging, and you can't deny the thrilling intoxication that comes from hearing "We Are Never Getting Back Together," "MYB," "Stacy's Mom," and "Sleepyhead" all converging at the same time. So it is with his newest gem, "Back with Stacy's Mom," which I've now had on repeat for 30 minutes. Find it on Soundcloud here. His 100k Bootleg Pack drops this Monday.
