UPDATE: Kacey won Album of the Year!

Kacey Musgraves did a captivating performance of the stripped-down "Rainbow" at the 2019 Grammy Awards ceremony, with a stage soaked in rainbow-colored lights and just a pianist joining her. She sounded great, and you can watch clips of the performance below.

Kacey also took the opportunity to drop the official music video for "Rainbow," and you watch that below too.

Kacey also performed with MusiCares Person of the Year Dolly Parton, doing Dolly's song "Here You Come Again," with Katy Perry joining them too. She rejoined Dolly at the end of her set for a big group performance of "9 to 5" (with Miley Cyrus, Maren Morris, and others). Watch that below too.

"Rainbow" is off her 2018 album Golden Hour, which won Album of the Year and Best Country Album. You can watch her acceptance speech for Best Country Album below. Kacey also won Best Country Solo Performance for “Butterflies” and Best Country Song for “Space Cowboy.” See the full list of winners and nominees here.
