For a band named the Concretes, this Swedish indie-pop ensemble’s music is surprisingly light and airy. Formed in the mid-1990s, the band garnered international attention with the bright, dreamy single, “Say Something New.” The main calling card was the sleepy, subdued voice of singer Victoria Bergsman, but when she departed in 2006 to perform as Taken By Trees, the ensemble soldiered on with longtime member Lisa Milberg at the fore.
