Atlanta’s 21 Savage is arguably the fastest-rising rapper on the planet, though his sound is cold, minimal, and uncompromising — in other words, far from the melodic trap rap of ATL contemporaries like Future or Young Thug. 21 represents a new wave of gangster rap coming out of Atlanta, complete with an element of shock value that starts with his hard-to-miss forehead tattoo of a knife. Anyone who’s clicked play on his debut mixtape, last year’s The Slaughter Tape, can testify that 21’s villainous image seems refreshingly authentic. His most recent project is Savage Mode, a collab tape with Atlanta super-producer Metro Boomin featuring his breakout hit, the Future-assisted “X.” 21’s accomplishments and accolades — whether it’s his spot on the XXL Freshman cover or appearance on new Drake single “Sneakin’” — are becoming impossible to ignore. That makes this Myth gig one of the most eagerly anticipated Twin Cities shows of 2016’s closing months. Chicago phenom G Herbo, another 2016 XXL Freshman, is also set to perform. All ages.
