Schoolboy Q and Kendrick Lamar light up lines and fondle syllables on “Collard Greens,” the latest single off Q’s highly anticipated album Oxymoron. Produced by Top Dawg’s repeating collaborators THC, Gwen Bunn and mixed by Ali, the beat drifts towards “Sacrilegious” on Q’s previous album Habits & Contradictions. That’s not a bad thing. The progression is crazy.
