New Town Drunks offer cozy exotica that overflows with low-brow sophistication and blithe goodwill. The casual mirth with which they greet their song-borne dysfunctions is redemptive, while their charm remains easy and unforced. Their initial releases were strummy and bright with a bubbly country-folk spirit, but increasingly theatrical elements have gained purchase. That development produces a smoky late-night cabaret vibe that suits the sultry croon and siren swoon of frontwoman Diane Koistinen. They're presently readying the follow-up to 2009's grower, The Ballad of Stayed and Gone. The show is a celebration of Mouse Mock, the longtime owner of The Cave who ended his stint underground last week. Lud opens. —Chris Parker
