Review: According to Denver, Colorado's Andrew Bon Bosher, try to imagine 'you're playing a level in a game, making great progress. Then you try to move forward off the beaten path, but the game won't let you. You just run into an invisible wall.' That pretty much gives you an idea of what to expect sonically on his Invisible Walls LP. From the reductionist junglisms of "Amen To The LS", "Bounty Trax" with its bass-driven techno bounce for warehouses, or moments of straight up brutalist dubstep like on "Spectral Umbra" which showcases this young producer's diverse arsenal within his repertoire.
