Seven years after their inception, All Them Witches sound punchier than ever on their 2018 album, ATW. The Nashville, Tenn., group perpetually laces Southern grit into its blues-infused brand of alternative rock. Though still plenty rough around the edges, the band’s latest effort glistens with refinement and showcases a wide breadth of stylistic mastery. Formerly a quartet, the trio blends heady psychedelia with soulful, dirty rock throughout the record, shifting from plodding and menacing to feverish and giddy. All Them Witches perform on Tuesday, March 19, at the Higher Ground Showcase Lounge in South Burlington. Plague Vendor open.
