The first offering of a four-part series of EPs issued in six-month intervals, Bound introduced the richly-textured arrangements of Birdsong At Morning with a decidedly laid-back, acoustically oriented sound. Each successive release would expand that palette, increasing both the tempo and energy. The remaining EPs – Heavens, Vigil, and Lumens – will be treated to similar immersive updates and released over the course of the next year, eventually gathered together into a single collection entitled Annals of My Glass House.
