Perhaps the name is a subliminal bit of wishful thinking, because these Montreal, uh, rockers? new wavers? Franco-popsters? never seem to stay still for too long. But the great part is that none of their many aural wardrobe changes sound contrived because they’re not mimicking styles; they’re bringing their own sound to bear on what’s out there. Their latest, “In the Beginning,” is a southern rock anthem. “Retour A Vega” is wistful even though I only understand every third word. And “Still in Love Song” is full of intelligent teen angst. So if you’re having trouble deciding what kind of mood you’re in, don’t bother with the shuffle on your iPod. Just load in the Stills and let them do the shuffling for you.
