Coming on the heels of previously-featured Closed Sessions cuts Fresh Like Me, Keep It Politics and Don’t Happen That Often, the last song release from RubyHornet‘s popular compilation is a Windy City two-fer. On So Stupid, The Cool Kids’ Sir Michael Rocks comes together with fellow Chi-town representative Vic Mensa (previously featured as a guest on Chance the Rapper‘s Family) to lyrically illuminate the thin, thin line that separates flyness from idiocy. Dilated Peoples member DJ Babu produces, crafting an off-kilter, chopped-soul-sample instrumental to back the Second City neighbors as they go dumb. Digging it? You’ll be able to find So Stupid, and much more on Closed Sessions Volume 2, released to the ‘net today. For more from Mikey Rocks, check out free ablum Lap of Lux, released early this month.
