It is a year since black teenager Michael Brown was shot dead by a police officer in Ferguson, Missouri.

The 18-year-old was unarmed and his shooting led to riots, both in Ferguson and across America.

Acclaimed rap band Run The Jewels are outspoken on racism and on the night that a grand jury decided not to indict the police officer that killed Brown - sparking the worst riots to date - they drove into the area to perform.

In this special video for the BBC, Killer Mike and El-P explain why they think riots work and what it was like to perform on such an emotive night.
