The 57th Annual Grammy Awards were held on February 8, 2015, at the Staples Center in Los Angeles, California.
The show was broadcast live by CBS at 5:00 p.m. PST (UTC−8). Rapper LL Cool J hosted the show for the fourth consecutive time.
The Grammy nominations were open for recordings released between October 1, 2013, to September 30, 2014. Breaking from tradition of a prime-time concert approach, the Grammy nominees were announced during an all-day event on December 5, 2014, starting with initial announcements on the CBS This Morning telecast, followed by updates made through The Grammys' official Twitter account.
