On their 12th release, art-pop act Stereolab float deeper into the post-rock atmosphere. They still draw from Ennio Morricone and Henry Mancini when creating their own fantasy soundtracks, but Sound-Dust lacks the dynamic interplay that invigorated Cobra and Phases Group Play Voltage in the Milky Night. The disc is all easy-listening lounge that's almost too gentle on the ears. There are no urgent sonic experiments, and only three tracks really spark to life: "Spacemoth," "Captain Easychord," and the Kubrick-inspired "Gus and the Mynah Bird." "Easychord" is the catchiest song on the album, containing the CD's most ebullient melody-emitting, warped, country-twanged notes. Beyond that, Stereolab fans should prepare for a very sedate, mature affair. --Jennifer Maerz
