The new remix set, Earth 2.23: Special Lower Frequency Mix, makes this clearer than ever. The Bug has taken a bit of “Seven Angels” and laced it with feedback and big bass, allowing grime luminary Flowdan to climb atop it with his dark, staccato visions. Responsible for many transformational records himself, Justin K. Broadrick of Jesu and Godflesh crawls inside “Teeth” to lash at it with punishing drum machines and sordid layers of new distortion, building it into some brokedown palace of industrial mayhem. Loop’s Robert Hampson makes good on the premise of ambient metal with his 30-minute hypnotic beauty, while longtime Earth cohort and longtime Built to Spill multi-instrumentalist Brett Netson seems to float the sound through a benighted graveyard on his clever “Teeth” revamp.
