Grandchildren take intricate orchestration, giving it an omnipresent percussive backdrop. The resulting sound is synchronized. Layered to establish complex grooves, rejecting gravitational force and instilling a floating ethereal quality. Providing a natural lift, this well-oiled machine offers palatable precision that can be broken down by the connections of its parts but succeeds in unification. Tonight at Bourbon & Branch, the casual folk/surf melodic warmth of Outside Eyes and Canadian indie-rock vets The Stills complete a lineup that will help you escape the weight of the week ahead. Bourbon & Branch, 705 N. 2nd St., 8pm $10, 21+ – Michael Colavita
