Since their mid-2000s reunion, the Backstreet Boys have been acting like adults so it's not entirely a surprise that they've decided to shake things up on This Is Us, their third album of the comeback and second since becoming a quartet.

Teaming up once again with Max Martin and working with a host of modern hitmakers as RedOne, the group takes a left turn back toward the rhythm-heavy, harmony-laden dance-pop that made their reputation a decade before.

Never mind the name of the album -- the group is tellingly quite willing to fade into background, letting the producers do their work, just content to sing the hooks.

It's a sharp move in two ways: BSB never had as much on-record charisma as *NSync, their best trait was how they could sell a hook without affect, and that returns here.

Of course, it helps that they have a bunch of hooks here, too -- hooks that aren't quite as galvanizing as "I Want It That Way," but easily eclipsing those on the pedestrian Unbreakable, helping the band seem modern without seeming pandering.

It's a move that the New Kids on the Block couldn't pull off on their tawdry, sex-obsessed comeback, and it's one that the Backstreets seemed incapable of doing just a few years ago, but on This Is Us, the group sounds great for their age, and they sound like they're at their peak -- which is no guarantee of a hit, but it sure makes for a better album than they've produced in quite a while.
