Beach House’s latest record, Thank Your Lucky Stars, has been out for a few months now. The dream-pop duo took the stage for a show in Luxembourg . During the set, Victoria Legrand and Alex Scally covered Weezer’s 1994 classic “Undone — The Sweater Song.” (Perhaps they felt inspired by the decidedly ’90s direction of the band’s new single, “Do You Wanna Get High?”) The original song appears on 1994’s Weezer. Beach House will be playing next friday at 2AM at Primavera Sound.
