Julianna Barwick is a composer, vocalist and producer who makes deep, reflective compositions out of the human voice. Over the past decade and a half, she’s honed an intuitive approach to music, built on improvisation and a close affinity to a couple of trusted items of gear. She spins engrossing, expansive universes out of a single idea. Her fourth album, Healing Is A Miracle, on Ninja Tune, marks another distinctive meditation on sound, reverb and the voice. Built out from the same instinctive, improvisational approach as those which preceded it, she also draws on the input of three collaborators she’s nurtured long friendships with: Jónsi (Sigur Rós), Nosaj Thing and Mary Lattimore, gently nudging out at the edges of Barwick’s organically-evolved sound.
