Chicago's newest sensations are the teenage Westside duo Sicko Mobb, who had only a few singles to its name before being signed to Sony via the publishing arm of Kelly Clarkson, Rihanna and Katy Perry producers Stargate. (Yes, that sentence is about as unfathomable as it seems.) But with just a few days left in the calendar year they've dropped their debut full-length mixtape Super Saiyan Vol. 1, which features previous calling cards like "Fiesta," "Hoes B Goin" and the Lil Durk-featuring "Maserati" as well as a bunch of new songs.

Sprouting out of Chicago's bop microscene, Super Saiyan Vol 1. is remarkably synthetic, with impossibly bright beats and rapping that's soaked through with Autotune. It is, of course, deliriously fun, the latest in a lengthening line of post-ringtone street-pop that might be more appropriate for Rainbow Road than an overflowing house party.
