Kid606 is a demigod among the pasty Pro Tools sect of electronic music. But listening to his previous records was like jamming a screwdriver into your cortex. So ”Kill” — which favors songwriting over pretension — is a revelation. Sheets of noise, bustling beats, and filtered samples remain in the mix, but Kid’s chaos theory is counteracted by acidic melodies and heavy metal posturing (sans the spandex and guitar solos). It’s intelligent dance music without the footnotes — and a call to laptops for anyone with a drum machine and a dream.
