Paramore's Reading Festival set hit by power failure Get Tickets
Band are left standing for 15 minutes as stage engineers struggle to restore the sound
Singer Hayley Williams, who was sporting a new green haircut, was in the middle of a speech about how the band "don't normally play slow songs" when the speakers blew on the Main Stage, leaving the band in silence for 15 minutes.
A spokesperson for Reading Festival told NME that the technical fault was caused by a fiber optic cable the band had brought with them for their production.
The Tennessee three-piece were mid-way through their set when the outage hit, following energetic performances of 'Still Into You' and hits from their back catalogue.

The whole band then sat down the front of the stage. Williams told the crowd: "A little update - the system is down but they're working on it. We're just going to pretend this never happened".
As sound engineers flooded the stage in an attempt to fix the problem, Williams entertained the audiance by theatrically miming a tantrum before leading a Mexican wave.
Williams then said: "I am the one that hates to play love songs at festivals. I want to play fast songs but right now we're going to do a love song, you and me a-cappella, it will be very special."
When the power was finally restored to a single microphone, the band played a stripped down version of ballad 'Only Exception'. During the track, Williams said: "Oh my gosh I'm never going to forget this. Alright Reading that was unbelievable."
After nearly 20 minutes, full power was eventually restored but at a much quieter volume than the early part of their set.
Later, during 'Misery Business', a woman dressed in a dinosaur suit got up onstage and sang the track with Williams.
Hailing headliners Queens Of The Stone Age, Williams added: "Queens Of The Stone Age are a band we've waited a long, long time to see play," before adding: "Today was a super eclectic group of bands on this stage and I want to commend you for loving music, all kinds of it."
Paramore wrapped up their set with 'Proof' and 'Ain't It Fun' from their 2013 self-titled album.
