The current Scream tour features the boy band Mindless Behavior, rapper Diggy Simmons (son of Rev. Run of Run D.M.C), singer Jacob Latimore, and the groups Hamilton Park and the OMG Girlz. (The California duo New Boyz were a no show on the D.C. date, their absence rumored to stem from a dispute with the tour’s organizers).

Things started with a history lesson about the tour, and the kids shouted even during this brief educational intrusion. Then the OMG Girlz, best known for “Pretty Girl Bag,” a remake of Soulja Boy’s “Pretty Boy Swag,” kicked things off in earnest. If Nicki Minaj and the Twitter bird reproduced, their offspring would resemble these adorable girls, with their blue hair and toy-encrusted corsets.

Diggy Simmons, who has been endorsed by Kanye West and, naturally, his dad, lived up to his hype. The kid perfectly straddles the line between teen idol and legitimate rapper, coming off as a less angst-filled Drake on tracks such as “Thinkin’ Bout You.”
