Considering the position of power they occupy in the West Coast underground pantheon, “Step Brothers” just doesn’t feel like a lofty enough moniker for Evidence and The Alchemist. The title of their latest collaborative feature, “Step Masters,” is more appropriate to their stature—or it would be, if it didn’t make them sound like a pair of exercise machines. In any case, the colleagues showcase mastery of their respective crafts on this cut, single numero uno off their collaborative debut. Over Alc’s grimy sample work, the partners-in-rhyme deliver wry, allusive bars about their paper chase, their smoking habits and their dominance over the competition. In Jason Goldwatch‘s hilarious video, brothers turn to rivals as the duo face off in a variety of challenges, from Jenga to egg-tossing. Fans can pre-order Lord Steppington now in anticipation of its January 21, release via Decon.
