10. The Black Keys
The Black Keys are one of a handful of bands from the last decade to graduate from clubs to arenas. At the dawn of the 2000s they were playing to just handfuls of people at tiny clubs across Ohio, but constant touring and recording slowly built up their reputation as a live powerhouse. Their 2010 LP Brothers was their commercial breakthrough, and "Tighten Up" went into heavy rotation on rock radio. Their 2012 tour is their first time headlining arenas, even hitting Madison Square Garden for two nights in March. The following night they headline the opening night of Coachella.
