Two Detroit natives and hip-hop veterans, MC Invincible and producer Waajeed, have joined forces on a fresh, new single, called “Detroit Summer.” The collaborative work is a sequel to the duo’s previous effort, “Detroit Winter,” and will be released by Emergence, Invincible’s own label, on 7″ and digital download prior to Invincible & Waajeed’s forthcoming full-length record dropping in 2011. “Detroit Summer” will come with the b-side, entitled “Emergence,” when it’s released August 10.
