The lead singer of a legendary punk rock band allegedly attacked a Trump supporter during a show in California last month.

Tim Hildebrand said that he suffered a bloody lip, two black eyes and a concussion while attending a Social Distortion performance at the Ace of Spades nightclub in Midtown Sacramento on July 17.

Footage of the incident shows 56-year-old frontman Mike Ness apparently spitting on a member of the crowd before taking off his guitar and jumping into the audience.

'I wasn't able to defend myself because people in the crowd were holding me back,' he said.

According to network affiliate CBS13, the tussle broke out after Hildebrand began jeering the singer while Ness trashed President Donald Trump and the United States between songs.

'I pretty much said I paid for your music, not your politics,' Hildebrand claimed in a self-recorded video clip captured on his cameraphone and later provided to CBS13.

He added: 'I stood pretty much with my silent protest with my middle finger up for the next two songs.'

That prompted Ness to motion for the California man to come towards the stage, where the notoriously curmudgeon frontman apparently spat in his face.

The clip shows the two start yelling at each other and as tempers run hot, the situation quickly escalates.

'[He] takes his guitar off, jumps off the stage and proceeds to punch me multiple times in the head,' Hildebrand said.

Another spectator at the show, Social Distortion fan James Mauldin, said that Ness acted unprofessionally and should not have attacked a fan, calling the scuffle 'a little bit excessive.'

But Mauldin also noted that controversy is part of the punk rock culture. 'If you're that into politics, don't put yourself in a situation where it could become a problem for you,' said Mauldin.

Hildebrand said that after the alleged attack, security guards escorted him from the venue where he filed a police report with cops stationed outside.

For the Republican and farmer from the nearby town of Galt, Hildebrand, who grew up listening to the Social Distortion, never thought he'd find himself in a physical confrontation with one of his musical heroes.

'Someone that has the status that he does shouldn't get away with assaulting someone,' Hildebrand said, adding 'If he wants to have a talk someday, man to man, I would love that but he would have to not be a child about it.'

For his part, Hildebrand is weighing whether to take action against the singer and collect damages.

A representative for the band has not responded to requests for comment.
