Keith Urban performed his newest single, 'Cop Car,' at the 2014 Grammy Awards on Sunday night (Jan. 26).

The four-time Grammy winner was joined by Gary Clark, Jr. for the special performance, adding a new dimension to the song.

'Cop Car' is the third single from Urban's genre-bending album, 'Fuse,' which saw him expanding his musical palette to work with multiple producers on groundbreaking tracks that reached outside his previous comfort zone.

The performance was highlighted by a furious guitar solo tradeoff between Urban and Clark, who was nominated for Best Traditional R&B Performance and Best Rock Song.

"I didn't realize how comfortable I was with all the country music," Clark told the Associated Press this week. "Throw a little twang on the guitar and see what happens."
