Meet Michele Lynn, the person responsible for Saturday’s 12-hour Winter Doldrums Folk Fest. Or maybe you already know her; Lynn has been playing bass with roots groups around town for more than 30 years. “I do not know how much time I’ve put into this event so far. If I were to add it up, I am sure it would be some crazy number,” she says. “But I won’t, because this isn’t really work to me at all; it’s very satisfying to be able to help other musicians out and spread their music. My day job is electrolysis, so during the day I get to help women who are plagued by excessive hair growth. And then the music is my passion and happiness.”

Winter Doldrums, she says, is about providing a platform for “amazing artists that most people will never hear of, yet their music is far better than anything you’d find on a top 20 list. Coming up with 16 acts for this show was easy; the hard part was narrowing it down, with so many amazing bands in the Philadelphia folk/Americana scene.”

The first half of the day features two exceptional young women: Brittany Ann, who Lynn lauds for a maturity in sound and lyrics beyond her 21 years, and Murchant, aka Annachristie Sadler, the Downingtown singer Lynn prizes for her “ethereal voice.” Five musicians, including Lynn, join Jess McDowell in the Wounded Healers to support her Americana originals. The Doldrums lineup is a motley crew, including urbane Irish expat John Byrne, folk-rocker Ryan Tennis (pictured) and an earnest-voiced singer-songwriter called Griz.
