Rock Action, the third full-length album from experimental noise outfit Mogwai, is a sort of compromise; it's out with harsh walls of feedback and allusions to Glaswegian gang warfare, and in with banjos, trombones, electronics, and for the first significant time on a Mogwai release proper vocals, from the band's Stuart Braithwaite. At 38 minutes, Rock Action is surprisingly brief it boasts a mere eight songs, two of which are pretty perfunctory bursts of noise: the Kid 606-style electronic distortion of "Sine Wave" and the molten industrial racket of "Robot Chant".
