Nashville-based Night Beds recently released Country Sleep, the band's debut full-length. Singer-songwriter Winston Yellen says it's the group’s first album out on a label but, “It doesn't put a stamp on anything, as far as a beginning. It just kind of feels like another step." The atmospheric-yet-sparse collection is stunningly pretty and emotionally intense — and a change of pace from the vigorously happy folk-pop onslaught of late. The band just had its TV debut on Late Night with Jimmy Fallon and has already received attention from Paste, NPR and Jools Holland. Night Beds headlines Emerald Lounge on Sunday, June 16. Jenny O. opens. 9 p.m., $8. http://www.emeraldlounge.com.
