Dave Matthews Band violinist Boyd Tinsley accused of sexual misconduct.

A Seattle musician who worked with Tinsley in Crystal Garden has come forward with harrowing allegations.

What started as a chance encounter at a San Francisco café and later morphed into a long-term professional relationship has become the latest story in the #MeToo movement. Following online musings and private legal action, a former colleague of Dave Matthews Band violinist Boyd Tinsley has made public accusations of sexual assault, harassment, and long-term grooming.

James Frost-Winn, a Seattle-based trumpet player who worked for Tinsley as a member of the band Crystal Garden from about 2015 through 2016, has accused the 54-year-old musician of making unwanted sexual advances and comments throughout the decade that the two knew each other. Frost-Winn, 28, tells Consequence of Sound that the two met in the fall of 2007 when he was homeless and struck up a friendship based on a mutual love of music and generosity the then-18-year-old had never experienced before.

The teen met Tinsley and his assistant by chance at the now-shuttered Peace Café, where they discussed music before Tinsley eventually bought Indian food and nice jackets for Frost-Winn and a fellow busker. They exchanged numbers and would meet up when Tinsley was in town, typically at his hotel room where they would catch up, watch movies, and smoke weed.

Throughout this time of intense musical creation, touring, and success for Frost-Winn, the trumpeter says Tinsley started exhibiting strange behavior. During a stop-over in New York in 2015, after spending three tour dates with DMB, Frost-Winn casually mentioned that he and some friends were going to watch the New England Patriots-New York Giants game at a bar. Tinsley, as Frost-Winn explains, “immediately got five tickets. When he did it, he said: ‘You better suck my dick or something.’ I thought maybe that was a funny joke or something, but it wasn’t also 100% joking.”

During Frost-Winn’s stint with DMB, he says Tinsley made a strange request before going on stage: he wanted a pair of socks. “I went to grab a clean pair, but he said, ‘No, I want the ones you’re wearing.’ So I gave them to him,” Frost-Winn says, adding that other musicians had confided that Tinsley had made the same request to them.

Csontos (who did not respond to a request for comment on this story) and Frost-Winn eventually calmed Tinsley down, and the recording session continued into the wee hours of the morning. As Frost-Winn fell asleep on the couch in the studio, Tinsley allegedly touched his legs, rubbed his back, and put his feet on his buttocks. “It not only creeped me out, but I thought it was really annoying because I was trying to sleep,” he recalls.

Frost-Winn eventually dozed off. “I don’t know how long I was asleep, but when I came to, he was masturbating next to me while I was sleeping, and he had his hand on my ass,” he says. “He was climaxing.” Frost-Winn freaked out and ran to another part of the house while Tinsley followed after him; he eventually came back to the studio.

“I sat there for hours; I was so freaked out,” he explains. “I felt assaulted. It was something I didn’t expect from him. I was contemplating how to stay in the project — it’s such a big opportunity, but my trust had been affected.”

Tinsley blamed the incident on “a pill mix-up” and said he wasn’t in his right mind.
