Faust vs. dâlek is one of the most highly progressive/regressive albums in recent memory. Strafing three nonconcurring sessions together under a fire of frothing percussion, seismic bass yawns and malevolent reverb, German aggressive angst editors Faust and New Jersey grit-spewing hip-hop trio dâlek maliciously test the membrane separating headspace from cosmic space. Not quite as dense and unforgiving as dâlek’s own material, or as unhinged and shard-filled as Faust’s, the staggering loops and drones of Alder still embody a well-informed primitivism, an urgent howl as the participants grapple with each other’s natures.
