With the ink still wet on their new deal with Stargate’s Stellar Songs/Water Music Publishing (Sony/ATV) and only hours left in the year, Chicago bop scene stars Sicko Mobb have dropped their debut mixtape Super Saiyan Vol. 1. The tape includes a rework of Chief Keef's most-beautiful "Citgo," a handful of song you've already heard -- "Fiesta," "Remy Rick Routine" and the Lil Durk-featuring "Maserati" -- as well as a dozen or so new addled, autonued and impossibly fun new ones. It's a joy.
