The 55th Annual Grammy Awards were held last night (Feb. 10), and it was business as usual for the famed awards show. Music's biggest names walked the carpet, while shiny golden gramophones were given out to rock artists such as the Black Keys, Halestorm and Trent Reznor + Atticus Ross. However, a sense of disarray resonated with various musicians, who took to Twitter in order to vent their disapproval of the Grammy Awards.

Out of any rock act nominated, the Black Keys were one of the night's biggest winners, having taken home trophies for Best Rock Album ('El Camino'), Best Rock Song and Best Rock Performance ('Lonely Boy') and Producer of the Year, Non-Classical for frontman Dan Auerbach. Halestorm took home a Grammy after 'Love Bites (So Do I)' won Best Hard Rock / Metal Performance and Nine Inch Nails mastermind Trent Reznor and his partner in sonic crime Atticus Ross won the Best Score Soundtrack Grammy for their work on 'The Girl With the Dragon Tattoo.'
