Very much getting into the spirit of raging against the machine, dozens of fans were filmed scaling the fence at The Rage Factor in Finsbury Park on Sunday.
Several videos posted on YouTube in the past 24 hours show a throng of people making a concerted push to get into the free gig.
Once the first wave scale the fence using the aid an electricity generator, many more storm the exit gate before security finally get to grips with them.
Although entry to the Rage Against The Machine Christmas chart victory gig were free only 40,000 tickets were available to the 200,000 registered fans leaving many disappointed.
Photo IDs on the tickets also meant they could not be passed on.
Many fans sat around the perimeter of the fence throughout the day enjoying the music peacefully.
It's not known how many people altogether bunked into the concert.
