A young Muhammad Ali sings with Sam Cooke.

After we posted that insane picture of Jesse Jackson ballin’ out with Marvin Gaye the other day and dubbed it a contender for peak blackness,  the homie Rembert Browne of Grantland decided to hit a few of us up — Ernest Wilkins of the Chicago Tribune, Cord Jefferson of Gawker, Jason Parham of Spook Magazine , Jenna Wortham of the New York Times, Issa “Awkward Black Girl” Rae and, er, me — to see if we can figure this thing out at peakblackness.tumblr.com.

Again, there are theoretical scenarios that would be inarguably the moment of peak blackness, but unless we find a way to transverse multiverses and dimensions, we’re never likely to see Harriet Tubman doing the wobble.
