Brooklyn indie hip-hop collective Das Racist has kept itself busy this year. Alongside the release of their first properly released full-length, 2011’s Relax, both of the group’s rapping members (Himanshu “Heems” Suri & Victor “Kool A.D.” Vazquez) have already released solo mixtapes in 2012. While both were uneven affairs, 51 (A.D.’s second of the year) is a surprisingly engaging effort that highlights Vazquez’s hyper-eclectic flow, versatile musical taste, and winning personality. Because they are such a Brooklyn group, it’s easy to forget that Vazquez is from the Bay Area, and 51 sees the MC embracing those roots with some dope cameos from some of the Bay’s leading lights, including Main Attrakionz, Amaze 88, Trackademicks, and legendary (in these parts) Coup frontman Boots Riley. Like a lot of mixtapes, it’s a little long, but Vazquez laid-back, electric flow makes sure that it doesn’t drag. This is possibly the best thing from the Das Racist camp since its brilliant 2010 mixtapes.
