Air first struck library-lounge gold more than a decade ago, and they're still digging that same vein they mined to uncanny perfection on 1998's Moon Safari, though for a while they've been oddly easy to miss. In fact, the downtempo demi-gods slash soft-prog wunderkinder issued an impressive six LPs in the '00s, and their distinctive alchemy of mood and melody has never faltered, even if it's grown perhaps more earthbound, less impossibly celestial. Love 2 (Astralwerks), their latest intastella burst, perks up from the super relax of 2007's languid Pocket Symphony with scuzzy space-rock, gossamer bossa-pop and future-retro spy-flick synths — nothing much new for the duo, sure, but they pull it all off with trademark Gallic aplomb, as natural as breathing.
