State of Emergency 4 finally announced just a few days ago that Migos, Jeezy and Gucci Mane will be their headlining performers at Chaifetz Arena Tonight.

If you're wondering how this concert series got started: 

According to HiphopDX, the event was started in 2014 in the wake of the turmoil in Ferguson, a suburb of St.Louis. Demonstrations triggered by the death of Mike Brown at the hands of a police officer, turned into unrest as demonstrators seeking justice clashed with authorities. 

Local rapper Young Dip wanted to inspire unity in the community. He helped set up the show on March 14 to coincide with "314 Day." Borrowing its name from the city’s area code, the local holiday focuses on creating goodwill and a sense of community among its residents.

State of Emergency 4 can be streamed tonight (March 14th) at 8:00PM EST/5:00PM PST  on REVOLT.tv and REVOLT TV
