What started as an earnest foray into pushing the boundaries of fledging math-rock, over the course of thirteen years has morphed into something much more for Canterbury (via Brighton) quartet Delta Sleep. Continuously surprising their listeners with every release by constantly tweaking and perfecting their sound, so far the bands expansive repertoire defies to be constrained by any strict sub-genre or category: molding their sound into something that goes beyond the labels of just math-rock.
