The Avett Brothers + Trampled By Turtles

Backed by a pulsing synthesizer and a dance floor beat, the lead single from the Avett Brothers' forthcoming album, Closer Than Together, is a fairly jarring departure from the group's catalog of folk-, country- and bluegrass-tinged tunes. Overseen by the vocal harmonies of Scott and Seth Avett, the stylistic evolution seems closely tied to some of the most overtly sociopolitical songs that the group has ever penned, which unpack the uncertainy of life in a world where fear is on the rise and longstanding values appear to be deteriorating. Headlining the Huntington Bank Pavilion at Northerly Island, the Avett Brothers are joined by folk act Trampled By Turtles.
