Lurking behind the ungainly name of First Aid Kit are beautiful Swedish sisters Klara and Johanna Soderberg who have just brought out the perfect summer soundtrack. Stay Gold, the band’s third album, is packed with great tunes and gorgeous harmonies. Neither so dreary as Haim, nor so noodly and wistful as many current female singers, First Aid Kit are┬árecommended summer listening with or without sunshine.
