Like master painters exploring a subject over a lifetime's work, Kevin Martin and Dylan Carlson - The Bug and Earth, respectively - have each been mining and defining their genres for more than 20 years. They're united by an interest in - really an obsession with - heaviness. They search for, examine and break the boundaries between beautiful and ugly, minimal and maximal, light and dark - but The Bug and Earth always make music that is heavy in the most thrilling of ways. 'Concrete Desert's' beautiful, chiming melodies are like shards of sonic light, glowing in currents of heavy bass darkness. There are pulsing soundscapes, ambient pinks and whites, and irresistible grooves. This is music that grips you entirely, and catches you in its lava-flow - an astonishing, primal album of vast depth.
