Among the many, many reasons to tune into tonight's ACM Awards, three of the biggest females in country music today are teaming up to premiere a brand new song. Host Reba McEntire, Miranda Lambert and Lainey Wilson are performing their song, "Trailblazer," for the first time anywhere. The song was written by Lambert, Wilson and Brandy Clark, and it will be made available once the awards show kicks off tonight. The ACMs will air on Prime Video and the Amazon Music channel on Twitch at 8PM Eastern/5PM Pacific tonight.
