PHOTO: At the 2013 Cornucopia Festival in October, Cranbrook’s Good Ol’ Goats proved their stage presence by belting out a solid set of traditional and roots-inspired songs. The youthful musicians are confident and proficient on their instruments, combining for a big and enthusiastic sound honed by years of collaboration in the high school band room. They play the Big Eddy Pub this Thursday, Mar. 20 as part of the Frostbite Music Series.
