Singer, songwriter, guitarist and “Boss Mama” Colleen Myhre has connected with a loose band of hard-rocking desperados and dubbed them the Jebberhooch. Together, Boss Mama and the Jebberhooch put out dusty, dirty, gritty blues that rumble across the stage like a beat-up sedan over a Mississippi Delta dirt road. Their sound is a shake-and-baked helping of country soul, harmony and groove.
