On Friday, Harrisburg, PA’s Quagmire Swim Team made its debut at Philadelphia’s Trocadero Theatre. Continuing the groups tradition of guest sit-ins in the City of Brotherly Love, the band brought out two members of Brothers during it set. Brothers Past guitarist Tom Hamilton appeared first on the Quagmire original ‘Black Joy’ while bassist Clay Parnell emerged towards the end of the set for another QST original, ‘Coming Back to You.’ Quagmire will perform next on July 21 at the Whitaker Center in Harrisburg, PA with the Avett Brothers.
