Gavin DeGraw and Lady Antebellum join New Year's Eve lineup with live performances from Nashville

"Dick Clark's New Year's Rockin' Eve with Ryan Seacrest 2015" begins live at 8 p.m. on ABC

Gavin DeGraw and Lady Antebellum are slated to perform on "Dick Clark's New Year's Rockin' Eve with Ryan Seacrest 2015" live from Music City's New Year's Eve Bash on Broadway in downtown Nashville. They join the biggest live music celebration in show history, featuring more than 38 performances and almost six hours of music. "Dick Clark's New Year's Rockin' Eve with Ryan Seacrest 2015" will air on Wednesday, Dec. 31, beginning at 8 p.m. ET/PT on ABC.

The bicoastal celebration will include hours of special performances and reports on New Year's celebrations from around the globe. Seacrest will lead the traditional countdown to midnight and, before the ball drops on New Year's Eve, Taylor Swift will perform live for more than 1 million fans in Times Square.

"Being included in such an iconic music event like 'Dick Clark's New Year's Rockin' Eve' further strengthens the Music City brand and Nashville as a destination," said Nashville Mayor Karl Dean. "We have seen the Jack Daniel's Bash on Broadway grow tremendously, and its inclusion on a national show is a natural extension of its growth and popularity. Lady A and Gavin DeGraw are great representatives of the music in our city, and we are excited to have them headline the night in Nashville."
