Previously heard collaborating on reader-approved loosie School Daze, Windy City neighbors SLOT-A and Add-2 have joined forces to Set It Off once again on the former’s latest feature—the first half of a “two-part leak” off his next solo set. Fresh off being dubbed a “Chicago Producer to Watch in 2013” by RubyHornet, Slot showcases the skills that earned him that title behind the boards, layering catchy piano chords over a explosive, syncopated rhythm section to back his and his partner-in-rhyme’s bombastic bars. The result is a high-energy cut that will undoubtedly bring down the house when performed in front of a live audience. The Transition is set to drop at midnight on Tuesday, February 5. In the meantime, fans can still click here to cop Have You Seen My Stapler?, Slot’s recent collaborative tape with Mike Schpitz, for free in the Booth.
