The Avett Brothers Rock Out, Share New Music on New Years 2019 [PICTURES]

The Avett Brothers welcomed 2019 with an uproarious New Year's Eve celebration in their home state of North Carolina on Monday (Dec. 31), in an evening that included family cameos, surprise appearances by the band in unlikely areas of the venue, new music and -- of course -- good old-fashioned, high-energy fun. Flip through the gallery above to see some of the highlights of the group's performance!

After a rousing opening set for country star Rodney Crowell, the group took the stage to get the festivities underway with a set that had something for every fan. The Avett Brothers played old hits, covered traditions and debuted brand-new material, such as "Who Will Hold Me When You're Gone" and "Willie Got There First," both of which the group performed live in concert for the first time that evening. The group first shared the latter track, a collaboration with Ray Benson and Asleep at the Wheel, back in August of 2018. Press play below to hear the group's live debut of "Who Will Hold Me When You're Gone."

As midnight neared, the hijinks continued: Bandmates Scott and Seth Avett and Bob Crawford snuck offstage and into a concession stand to play a surprise two songs for anyone who might have happened to step away for a snack.

When the clock struck midnight, the band celebrated with balloons and confetti, and sang "Auld Lang Syne," the words and music of the traditional song projected onto the backdrop behind them so that the audience could join in.

In 2019, the Avett Brothers will return to Red Rocks in Morrison, Colo. for a three-show run in July. During one show on July 7, they will be joined by supporting act Lake Street Dive, with no word yet on the opening bill on the other two dates.
