Today in 2014 Led Zeppelin won their first competitive Grammy Award. It was Best Rock Album for Celebration Day, the recording of their 2007 one-time benefit concert at the O2 Arena in London.
This was actually the first Grammy win of Led Zeppelin’s career. They were awarded a Lifetime Achievement Grammy in 2005, and they have 2 albums (I and IV) and 2 singles (Whole Lotta Love and Stairway to Heaven) in the Grammy Hall of Fame. In 1969 they received their first and only previous Grammy nomination (for Best New Artist), but lost to Crosby, Stills & Nash.
