Led Zeppelin, Black Sabbath Win Rock, Metal Grammys
Sabbath won Best Metal Performance for the song 'God is Dead?' from their 2013 Ozzy Osbourne-reunion album '13,' beating out young whipper-snappers like Anthrax (who were covering an AC/DC song), Dream Theater and Killswitch Engage.
Led Zeppelin won Best Rock Album for 'Celebration Day,' a document of their one-off 2007 reunion concert which was released in late 2012. They beat Black Sabbath, Neil Young, David Bowie, Kings of Leon and Queens of the Stone Age for this award.
Continuing classic rock's domination of the early awards, Paul McCartney racked up five Grammy Awards before the main show even started, including a Lifetime Achievement Award for the Beatles, a packaging award for a Wings live album, and various awards for his 2012 'Live Kisses' collection.
