Experimental-electronic act The Demix kicked off March with a new EP. Consisting of material he’s been playing live over the last year, “ARRIVAL” brings all the hyper-driven electronica you could need to get amped up. Whether it’s by way of a caffeinated bass blast or an ominously textural atmosphere, there’s a masterful, tried-and-true versatility to the artist’s attention to detail here. The Demix goes full turbo with “ARRIVAL.”
