Once upon a time, a weekly hip hop show brought together Duval’s best battle-rappers, MCs and DJs. Now Hip Hop Hell is being resurrected to deliver only the best local and national acts, with two events this week at rain dogs. On Saturday, critically acclaimed Detroit producer MC Black Milk brings the beats with a special DJ set; on Tuesday, local hero Tough Junkie is on with Mega Ran. Ran’s Chip Hop style, mixing 8-bit chip tunes and fluid storytelling, was featured on Portlandia and Tosh.0, so there’s that. Black Milk 9 p.m. Aug. 9, $10; Mega Ran 9 p.m. Aug. 12, $5, rain dogs, Riverside.
