Somerville Songwriter Sessions at the Armory Cafe presents contemporary folk singer/songwriters in concert, usually on the first Saturday of each month. (Our September show is delayed a week due to the Labor Day holiday.) The Armory Cafe features live music in an intimate setting, a menu featuring sandwiches, soups, desserts and coffees, and plenty of free parking. Please note that all attendees are encouraged to wear a mask except while eating or drinking. Our 9/10 performers:

Sam Babineau is a songwriter and fiddle player hailing from the South Coast of Massachusetts. She enjoys engaging with personal narratives that echo the storytelling found in traditional folk music, blended with a modern zest. Her introduction to Irish playing began with her involvement in Irish step at the age of 10. Since then, she has adapted her background of fiddle music to support her songwriting. She finds inspiration in artists with deep folk roots such as The Staves and Lady Maisery. More at sambabineau.com.

Glimmer (Jocelyn Limmer) is a Boston-based singer-songwriter and keyboard player whose lyrics are inspired by matters of the heart, patterns of the mind, and the sometimes-labyrinthine journey towards self-love. Drawing from a range of influences from Fiona Apple to Queen to the Supremes, Glimmer writes piano ballads and soul-pop songs that explore the shifting fault line between heartbreak and healing.

Rachel Marie follows in a tradition of unapologetically forthright women folksingers, with songs that hearken to "overstuffed lines of Tori Amos, philosophical turn of Indigo Girls, and lilting vocals like Joni Mitchell." The social awareness of folk meets the introspection of the singer-songwriter tradition with a moderate dose of snark. An endearingly quirky stage presence as honest as her songs keeps audiences charmed. More at rachelmarie.com.
