Run The Jewels on Ferguson: 'Riots work'
6 August 2015 Last updated at 00:09 BST
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.
