Mother Sun is Jonathan Cordle and Christopher Haynes, along with various friends at various times. The duo met in Pittsburgh and very quickly started making music together, first as music school students receiving formal training, then around the local clubs and gallery circuit. In bands of varying sizes for a few years, Cordle and Haynes produced artsy post-rock, dense art-pop, and neo-classical indie-psychedelia, working with a few other musicians from the Pittsburgh scene.
