Took place last night in Los Angeles The Grammy Awards 2013. And this year, the music seems to have changed. The best-known names gave way to artists on the crest of a wave for less time, but in 2012 they made a difference, winning audiences and critics. We're talking about The Black Keys, Mumford & Sons, Gotye. "Outsiders" who have overturned the odds and stole the show with two super favorites Jay-Z and Kanye West have settled awards reserved for their category, Rap and R & B. The best album of the year, in fact, was one of the brothers Mumford, while The Black Keys are the new rock stars of the world.
