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, and 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
telecast, followed by updates made through The Grammys' official CBS This Morning Twitter account.  Sam Smith won four awards, including Best New Artist, Record of the Year, Song of the Year for " Stay with Me" and Best Pop Vocal Album for . In the Lonely Hour Beck's album was named Morning Phase Album of the Year. This prompted Kanye West, who later said he thought Beyoncé should have won, to jokingly leap onstage to interrupt Beck in a re-enactment of his 2009 MTV VMA scandal, but West left the stage without saying anything. Both  Pharrell Williams and Beyoncé took three honors; with her wins, Beyoncé became the second-most-honored female musician in Grammy history following Alison Krauss. Lifetime Achievement awards were given to the Bee Gees, George Harrison, Pierre Boulez, Buddy Guy, and Flaco Jiménez. 
In all, 83
Grammy Awards were presented, one more than in 2014. 
The show aired simultaneously on
Fox8 in Australia,  Sky TV in New Zealand, and on  Channel O in South Africa. 
Not all Grammys were presented during the live telecast. As in previous years, most awards were handed out during the so-called
pre-telecast ceremony, held at the Nokia Theater next to the Staples Center, which takes place during the afternoon before the main show. From 2015 on, this ceremony has been known as the Premiere Ceremony. Approximately 70 Grammys were presented at this ceremony, consisting of the "minor" categories.
During the ceremony, United States President
Barack Obama delivered a pre-recorded message in which he spoke about domestic violence against women. His message was followed by a plea from domestic violence advocate Brooke Axtell and singer Katy Perry performing her ballad " By the Grace of God" as a dedication to the victims of the crime.

The following received multiple awards:
As usual, had a number of small changes in the voting and awarding process:
Best American Roots Performance is a new category in the American Roots genre field. It was presented to the creators of the best performance in this genre field, which includes traditional Northern American (or regional roots) musical styles such as cajun, zydeco, polka and others.
Another new category is the Best Roots Gospel Album in the Gospel genre field, for gospel albums in the aforementioned musical styles, including traditional southern Gospel music.
Changes in the Gospel categories
The Gospel genre field was redefined to make a clearer distinction between the traditional gospel music and the style known as Contemporary Christian Music (CCM). As mentioned above, the
Best Roots Gospel Album category is new. The categories in the Gospel field will now be known as , Best Gospel Performance/Song , Best Contemporary Christian Music Performance/Song , Best Gospel Album and Best Contemporary Christian Music Album .
Best Roots Gospel Album
For the first time, the use of samples and/or interpolations of other works in a new track was permitted in the various songwriters categories. Until now, samples were only allowed in the
Best Rap Song category, but these are now also eligible in the Song of the Year, Best Rock Song, Best R&B Song, Best Country Song, Best Gospel Performance/Song, Best Contemporary Christian Music Performance/Song, Best American Roots Song and Best Song Written For Visual Media categories.
