To celebrate the release of their forthcoming, collaborative, 4AD-released album Planetarium - out 9 June - Sufjan Stevens, Bryce Dessner, Nico Muhly and James McAlister have revealed a stunning second single. 'Mercury' centres around the heart-wrenching vocal beauty fans of Carrie & Lowell will recognise, as the hushed melody pours out above the increasingly other-worldly, filmic accompaniment. The adjoining LP revolves around the ideas Stevens’ lyrics explore: mythology, astrology, science, astronomy and the intricacies of human consciousness. Gorgeously atmospheric work from a dream indie super group. -G.O'B
