Don’t expect Daniel Higgs to rehash drone-rock band Lungfish’s glory days at this late date. The vocalist/guitarist/Jew’s harpist has gone off on an odder tangent since his legendary Dischord Records group went on hiatus in 2005. Now Higgs makes genuine freak folk—Sandy Bull as imagined by Flannery O’Connor on absinthe—that’s a conduit to spirit worlds of unfathomable beauty. Higgs’s rock past sometimes resurfaces, but it’s filtered into a gnarled backwoods surrealism that could scare the bejeezus out of Will Oldham. (Cairo, 507 E Mercer St, 453-4077, 8 pm, $7, all ages)
