The lead singer of rock band Brass Against was filmed on video pulling down her pants and peeing on a fan's face during a concert in Florida.
Sophia Urista, the band's frontwoman, shocked crowds with the crude display at the Welcome to Rockville festival in Daytona.
The band, known for covering songs by bands such as Soundgarden and Black Sabbath, was performing a rendition of 'Wake Up' by Rage Against the Machine when the incident occurred.
After inviting a fan on stage, Urista instructed him to lie down. She then proceeded to pull down her trousers and appeared to urinate on his face, while still performing the song, TMZ reports.
Those at the show in Daytona Beach, Florida, and people watching the clips online branded the moment "disgusting".
The disturbing stunt was captured on video by people who were just feet away watching it unfold in the crowd. The man then got up and spewed up some of the urine in the direction of the audience.
The New York-based band has since apologized for the stunt and said Urista got "carried away".
"We had a great time last night at Welcome to Rockville," they said in a post on Twitter. "Sophia got carried away. That’s not something the rest of us expected, and it’s not something you’ll see again at our shows. Thanks for bringing it last night, Daytona."
The band's Facebook page, which boasts over 450,000 fans, describes them as "a collective with the goal of creating music to inspire social and personal change".
Before the ordeal, Urista was heard telling the crowd that she needed to urinate.
"Get my man with the can on his head ready, 'cause we're going to bring him onstage and I'ma p*** in this motherf***er's mouth," she said. "I gotta pee," she added. "And I can't make it to the bathroom. So we might as well make a show out of it."
The comments were turned off on that post, but several Instagram users gave the band a mouthful in their previous post, which announced a European tour.
"Now is the urinating on people a VIP experience?" one user wrote. "Will you be p***ing across Europe?" another quipped.
"These people are losing their sanity.. Its disgusting," another wrote.
Others, however, suggested that the man who was brought up on stage was a willing participant who didn't seem to be disturbed in the video footage.
"Yeah ... the guy literally wanted it to happen. I’m not supporting it in any way but I don’t think [Urista] should be entirely to blame here," one person wrote.
