SAN FRANCISCO -- A fundraiser took place at a San Francisco club Monday night to help defray the medical bills facing the family of a teenage musician who was injured in an illegal firework accident during the Fourth of July holiday.

It was only fitting that the benefit concert at the Hemlock Tavern on Polk Street in San Francisco featured a punk-rock band with a female drummer. This is the type of music that 17-year-old Roisin Isner played in as a drummer for the band Tinkture.

Roisin was at Dolores Park on the Fourth of July watching San Francisco's fireworks show when someone threw an illegal explosive that went off near her right hand. She spent ten days in the hospital and her right index finger had to be amputated.

"My hand won't ever be the same again. It will be different, but it won't be bad. There's nothing wrong with it," explains Isner. "The index finger is one of the least important fingers on the hand and my middle finger is going to naturally take over its functions. I still will be able to write, draw and play drums."

Roisin says this has been a life changing experience. She has no health insurance, but is overwhelmed by people offering to help.

Besides the concert Monday night, there was a raffle and t-shirt sales to help defray medical costs. All of this was organized by Nicole Sloate, herself a drummer. She left Dolores Park early that night because of the illegal fireworks going off.

"It just kinda hit really close to me, not only because all of my friends were in the park that day and it could have been any one of us," said Sloate. "But [it's] even worse that it was a 17-year-old upcoming woman musician. I feel very strongly about that."

Police did arrest a 17-year old for possessing illegal fireworks but have not yet linked him to the explosion that injured Roisin. She says she could care less about catching that person.

"Everything I'm doing now is to try and get better and to try and heal. That's all in my future, and the person doesn't have a place in my future," says Isner. "I don't care about the person. My goal is I want to get my hand rehabilitated to the point where I can play again and as good as I used to or even better. I still want to improve."

Isner will be studying biology at Dominican College in Marin this fall. She says during the repair of her hand there was a skin graft from the removed finger and she may have a finger print on her knuckle. She describes it as "real cool."
