Following the pair's collaboration on "Russian Roulette," rappers Fat Trel and Chief Keef have teamed up once again for "Fukkk da Feds." It's produced by Lex Luger and features nonstop snare rolls on top of chest-pounding drums and some muffled synths. Apparently Trel and Keef have more material recorded together, which is good because neither rapper outshines the other while they both hold onto their own styles. Plus, "Feds" kicks off the best opening line. Just listen below.
