Backstreet Boys

An on/off phenomenon since 1992. Maybe it's time to call these swoon-seducing, world-centric popsters the Backstreet Men? Fellow former teen (weren't we all?) Avril Lavigne flaunts grown-up moves in the opening slot.

Nikki Lane

We're digging this tough-struttin' country rocker, a hell-raiser celebrating "It's Always the Right Time to Do the Wrong Thing." Dan Auerbach (Black Keys) produced Lane's "All or Nothin'" long player, so you know she's got good taste as well as passion. Max Gomez makes a worthy opener.
