I loved what Boston Phoenix music writer Michael Brodeur had to say about Stereolab in his recent feature pertaining to the band's new (and ninth) studio album, Chemical Chords: "You'll often, in reviews, see Stereolab treated with the same encouraging shrug one might offer a reliable furnace after it switches on each year." True that. Sure, the long-running Anglo-Franco band haslike Spiritualized, perhaps Sonic Youth, toofound a (ahem) sonic comfort zone to operate within at this stage of their career, and so there typically are few stylistic leaps and mutations to be spied from disc to disc. Still, there are always new pleasures to be heard in the group's retro-futuristic grooves, whether it's a fresh set of Moog-tastic melodies, Laetitia Sadier's Marxist coo, or the way they continue to rub together krautrock, art-rock drones, and '60s lounge-pop in colorful, appealing ways for every outing.
