Sigur Ros is apologizing to fans for a high-profile gig gone awry. The band's performance at Bestival in the U.K. was thrown off by requests made by headliner Stevie Wonder. Sigur Ros had demanded that they perform in darkness, but their set was moved up into daylight.

This clearly miffed the band, who then refused to allow their set to be streamed online (all other performances from the festival were). After the event was over, they took to their website to explain why they chose "to draw a discrete veil" over the performance, adding that they had a "thoroughly miserable experience on stage."

Wonder, Florence + The Machine and The xx were among those to play the festival.

Bestival was also marred by far graver news. A bus carrying 50 festival goers from the event overturned, killing the driver and two passengers and leaving many others injured. Authorities said some of those injured are likely to lose limbs.

Here's Sigur Ros' full statement:

sigur rós would like to apologise to anyone disappointed not to see the band’s bestival performance live online last night. early in the day a decision had been made to delay broadcast till after the show to give the band a chance to review the footage ahead of webcast, since they were dismayed that their guaranteed “darkness” slot had been pushed into daylight by the expansive demands of the headliner. the band’s only uk show of the year, this would-be highlight of the 2012 calendar, would have to be conducted without proper lights or visuals. sadly then, a perfect storm of production issues and technical problems conspired to mean that the band went on to have a thoroughly miserable experience on stage too. and to spare everyone’s blushes a decision was made to draw a discrete veil over proceedings. sorry, but we can be so much better than what you missed. another time, for sure.
