Musicians who make drum’n’bass, electronic pop’s avant-garde extreme, often incorporate the sounds of video games and children’s toys. Bogdan Raczynski mines everything from tin xylophones to windup noisemakers, plus a wide array of modern synthesizers, to construct his purposefully distracted music on Boku Mo Wakaran (Rephlex). Perhaps this vein of sampling is intended to provide familiar focal points amid the hallucinogenic goings-on. More likely, though, those sounds are important touchstones — the sonic memories that inform Raczynski’s work, most of which bounces around with the pace of an arcade game. The bass end hums like an ominous, circling death ray, while melodies (or their nearest equivalent) ricochet about at maddening speeds. There are moments of peace among the 26 tracks here, notably the elegiac closer, but Raczynski loses patience with patience fairly quickly.
