Trampled by Turtles + Hurray for the Riff Raff

Minnesota quintet Trampled by Turtles takes the high-tempo thrash method of Slayer and applies it to bluegrass, with some seriously furious fiddling and banjo- and mandolin-strumming. In the opening slot is Hurray for the Riff Raff, the edgy blues-folk collective led by the Bronx's own Alynda Lee Segarra.
