Charleston-based quintet Susto has been building a following for their brand of folk-rock through consistent touring. The maturity of the band’s newest album, & I’m Fine Today — due out the day of this show — will only help the cause. There are hints of psychedelia, indie rock and textural landscapes that push the band’s sound to the furthest edges of any Americana labels. Songs like “Gay in the South” redefine their lyrical substance, as well.
