Within their first year, OER have played with Her Name Is Calla, Evi Vine, Totorro, Waking Aida, Vasudeva, Polymath, UpCdownC, Those Amongst Us Are Wolves, Vasa and Memory of Elephants, among many others. They blend prog and post, riffs and gentle melody, loud and quiet, power and emotion, leading to an emotive and engaging listening experience, whether live or on record. OER’s music takes listeners on a journey through hope, loss and back again by way of intense, climactic post-rock, bursting with the sounds of empty space.
