Cosy Sheridan last played a concert for the Bozeman Folklore Society back in 2013, in the Chris Boyd Room at Pilgrim. She has won songwriting contests at the Kerrville Folk Festival and the Telluride Bluegrass Festival. Backed by the strong rhythms and harmonies of her bass player, Charlie Koch, she plays a percussive bluesy guitar style.

The concert will be outdoors on the north lawn (or in the Boyd Room if it rains). BYO blanket or chair. The show time is 7 p.m. Ticket sales begin at 6:30. Tickets are $20 each.
