Portland electro goes cruising for a bruising. Ten artists stumble around a house of sharp metallic corners and unforgiving doorframes in the dark, accumulating the sonic equivalent of scrapes and cuts. By far the most intriguing tracks are the ones that are the most energetically masochistic: Solenoid’s “Genclone 4” lurches out of every groove as soon as it settles into it, smacking itself brutally around. “She’s A Doctor, Too” and “Monkey Feet,” both by ML, are the most compelling, full of swaggering postures and sly hooks.
