The band, made up of members of politically charged rock and rap acts Rage Against the MAChine, Cypress Hill and Public Enemy, performed a free gig at an anti-poverty rally in the city on Monday (18Jul16), the opening day of the political event.

The RNC's presence in Cleveland has sparked protests across the city due to the U.S. Republican Party's likely nomination of controversial billionaire Donald Trump as their candidate to contest November's (16) American presidential election.

Towards the end of the gig, Prophets of Rage star Tom Morello, who also fronts Rage Against the MAChine, told fans and activists, "Thank you for coming out today with your joy and your militancy We're gonna play one more jam, then we're gonna go over there (to the RNC) and you're gonna go over there and we're gonna let those motherf**kers at the RNC know that we've had enough of their bulls**t."

The band then proceeded to play Rage Against the MAChine's 1991 hit Killing In The Name Of, before the crowd marched towards the Quicken Loans Arena, where the convention is being held behind a tight security perimeter.

After reaching Cleveland Public Square, a site just a few blocks away from the arena where the convention was already underway, the band set up their equipment and played another protest gig.

A ticketed Prophets of Rage concert is scheduled to be held on Tuesday (19Jul16) at the city's Agora Theatre & Ballroom, while bandmembers are believed to be planning other events before the RNC closes on Thursday (21Jul16) having dubbed their protests 'The Battle of Cleveland'.

The supergroup, who formed earlier this year (16), also released their first studio material as a band on Monday (18Jul16), a new version of the Public Enemy song they take their name form.
