Booth newcomers Fraction & Fresh Kils don’t just drop science—they drop Extra Science. What precisely does that entail? To find out, you’ll have to take a listen to the Ontario emcee-producer twosome’s newly-leaked EP title track, which finds Fresh Kils cooking up a retro-informed backdrop (complete with old-school cuts) as his mic-rocking partner delivers vivid, tightly-wound verses. Feeling it? You can find this cut and much more on Extra Science (the EP), available in stores and online as of April 5.
