Katy Perry, dressed as a cowgirl with a sparkly magenta microphone, made a cameo to duet with Dolly Parton, while Chris Stapleton had yet another successful night collecting trophies on Sunday at the 51st Academy of Country Music Awards.
Mr. Stapleton, who was the breakout star of last year’s Country Music Association Awards and also won his first two Grammys in February, topped the country field again with four televised awards (and two more off-camera), for best new male vocalist, album of the year (“Traveller”), song of the year (“Nobody to Blame”) and male vocalist of the year.
Jason Aldean, who like many of his peers has performed songs written by Mr. Stapleton, scored the top prize, entertainer of the year, over the genre fixtures Garth Brooks, Luke Bryan, Eric Church and the category’s lone woman, Miranda Lambert. (Mr. Stapleton was not nominated, although his recent omnipresence in country music was the gag in the night’s opening monologue.)
“I may be a little rough around the edges, but I love this business,” Mr. Aldean said in his acceptance speech.
Other winners included Ms. Lambert for female vocalist of the year; Florida Georgia Line for vocal duo of the year; Thomas Rhett’s “Die a Happy Man” in an upset for single record of the year; and Kelsea Ballerini for new female vocalist of the year.
Ms. Ballerini, like Ms. Parton, also brought a pop star — Nick Jonas — to spice up her performance. Other musical highlights included Mr. Church’s subtle-enough tribute to recently deceased rock stars (David Bowie, Glenn Frey, Lemmy Kilmister, Scott Weiland) and the usual vocal acrobatics from Carrie Underwood, who performed her new single about domestic violence, “Church Bells.” The performance-heavy show also featured Tim McGraw, Little Big Town, Sam Hunt and Kenny Chesney.
None, of course, had the Technicolor spice of the “Dolly & Katy” show. Ms. Perry, who has said she wanted to bring out Ms. Parton during her Super Bowl halftime performance in 2015, joined this country legend for the hits “Coat of Many Colors,” “Jolene” and “9 to 5.”
“Y’all finally got me in a pair of boots,” Ms. Perry said.
The show, which was broadcast live from the MGM Grand Garden Arena in Las Vegas on CBS, was hosted by Luke Bryan and Dierks Bentley. Winners of the televised awards are determined after three rounds of voting by the Academy of Country Music’s professional membership. (An eight-year experiment in which fans also contributed votes to Entertainer of the Year and three other categories was discontinued for the 2016 awards.)
