Duelin' Viola brothers "Salt Thief" are back at Tractorgrease Saturday, April 6th. Pushing the limits of how much ruckus can be made by two humans and their fiddles, the Brothers K holler out songs of whiskey, sagebrush, love, yodeling, The Other Side, pirates, bicycles, and skeletons dancing in the grave. Aided by their friendly beards and mighty violas, Tony and John easily walk the not-so-fine line between bellowing fury and cosmic sentimentality. ticket. Tickets · $15 via Eventbrite. Find Tickets
