If you like your drum & bass to go deep and ride half-time, lock into this one from Berlin's music composer, publisher and researcher, Felix K. Presumably influenced by the subterranean depths of the murkier corners of his hometown, these are menacing cuts that stay low but hit big. The undulating drums have predatory energy as the percussion dances about up top, never staying in once place too long, just like your focus. Some are widescreen and sparse, others more tightly coiled, all of them are brilliantly kinetic and fluid, hypnotising and ultra fluid.
