Lynn has studied and sung traditional ballads since childhood, inspired by Joan Baez, Judy Collins, Maddy Prior, June Tabor, Shirley Collins, Anita Best, and source singers from collections by Edith Fowke, Helen Creighton, and Helen Hartness Flanders. She has more than 30 Child ballads by heart, and loves to sing them back to back on long car rides as well as at festivals and folk clubs. For forty years, every Halloween at midnight by candlelight, Lynn sings the 44-verse shapeshifter ballad of Tam Lin,  learned from the great Ewan MacColl and since passed on to young ballad singer and collector Nora Rodes. 

In hundreds of monthly sessions since 2020, Lynn has gathered ballad singers from the West Coast to the UK and Europe in her online folk club, The Mermaid's Tavern, to sing the old ballads that still ring true with raw stories of human life. Each year in February, the Mermaid's Tavern celebrates the birthday of Francis James Child with a special session devoted to the many versions and variations of the 305 Child ballads. 

A former president of the Folk Song Society of Greater Boston, Lynn Feingold frequently organizes ballad circles, trad swaps, and the occasional “Ballads Around the Firepit.” She loves to host late-night ballad sings to hear older performers share the songs of their youth, working knee to knee with celebrated tradition bearers like Anita Best of Newfoundland. She performed traditional music of the colonial days for 27 years at Blanchard's Tavern in Avon, MA, with a repertoire ranging from Child ballads to tender love songs and hearty drinking songs. 

Lynn and her sister Karen Haffner are co-organizers of the Traditional Ballad Singing Competition for Students held in Kingston, MA. The goal of the contest is to expose young people to traditional ballads and encourage their research, learning, and performance of a traditional ballad at the contest -- for cash prizes. Everyone who stands at the mic and delivers a ballad gets a modest cash prize, and every young person in the hall gets exposed to all the other ballads being performed by the contestants. The hall is packed with adoring fans of the young performers.
