Details are coming to light today about a brawl between Bloc Party frontman Kele Okereke and the Sex Pistols' John Lydon, as well as members of the latter's entourage. The altercation took place backstage Saturday at Spain's Summercase festival.

Okereke, who describes the fight as an "unprovoked racist attack," endured "severe facial bruising" and a "split lip." He says he approached Lydon backstage at Summercase to ask if he'd ever reunite with Public Image Ltd., one of Okereke's favorite bands.

But according to Okereke, Lydon then "became intimidating and aggressive while his entourage responded with a racist tirade including the statement, 'Your problem is your black attitude.'"

A fight quickly ensued between Okereke and three members of Lydon's entourage, with Kaiser Chiefs frontman Ricky Wilson and Foals lead singer Yannis Philippakis becoming embroiled as well. Festival security broke things up but the altercation was reported to both Spanish and U.K. police.

"It's not an issue of the physical assault, even though it was an unprovoked attack, it is the fact that race was brought into the matter so readily," Okereke says in a statement. "Someone as respected and as intelligent as Lydon should know better than to bring race into the equation, or socialize with and encourage those who hold such narrow-minded attitudes. I am disappointed that someone I held with such high regard turns out to be such a bigot."

Lydon is blaming the entire incident on "jealousy," saying in a statement that "When you are at a festival with bands who are jealous fools, lies and confusion usually follow. If they need publicity so badly, this is the allegation universe they run into."

The artist further says that Okereke should "grow up and learn to be a true man. When you have achieved as much as I have, come back and talk to me. It's a shame that the wonderful world of the media is riddled with nonsense like this."
