Florida Georgia Line is helping to kick off the new season of ABC's "Nashville."  The country duo delivered a live performance of their current hit, "Dirt," to bring Wednesday night's season three premiere to a close. 

Florida Georgia Line gave one of three live performances during the show, which marked the first time live segments have been incorporated into a scripted, pre-taped TV show. 

"Nashville" star Charles Esten joined Florida Georgia Line for their performance, which took place after he - as Deacon Claybourne - sang the new song "I Know How To Love You Now."  Chris Carmack gave the first live performance just a few minutes into the episode, singing "If It's Love" as Will Lexington.  Esten and Carmack's songs are available now from iTunes. 

The live segments were woven into the plot, with the characters referencing a nationally broadcast TV concert special that night as they lived out their off-stage dramas. 

And another real-life country star will be featured on next week's episode.  But Luke Bryan's guest appearance won't be live.  He taped his scene with "Nashville" star Connie Britton - Rayna Jaymes on the show - and "Good Morning America" news anchor Amy Robach in New York last month.
