Brooks and Dunn ACM - H 2015

Luke Bryan and Blake Shelton co-hosted the 50th annual awards.

Brooks & Dunn performed "My Maria" at the Academy of Country Music Awards (ACMs) on Sunday night at the AT&T Stadium in Arlington, Texas.

To close out the show, the duo belted the falsetto notes to their country hit on a candle-lit stage. Their performance marked the last of the night.

Fellow artist Keith Urban referred to them as the "greatest duo in country music history" as he presented the pair with the milestone award following their set.

The longtime country duo most recently took home top vocal duo in 2007.
