BANGOR — After selling out headlining concerts in New York, Los Angeles and Nashville, ACM and CMA Vocal Group of the Year Lady Antebellum will bring its “Need You Now Tour” to Bangor Waterfront Pavilion on Labor Day, Monday, Sept. 5.

Fans of the Grammy Award-winning country trio may buy tickets at WaterfrontConcerts.com, by calling 783-2009 or in person at Mark’s Music in Brewer.

“I feel like we were just writing songs for our very first show at this small club in Nashville,” said Hillary Scott. “I can remember being so nervous to perform in front of just a handful of people that night and to think now we’re beginning to headline our very own tour is unbelievable. We have our fans to thank for following us every step of the way and can’t wait to show them what we’ve worked up.”

The trio’s triple platinum album, “Need You Now,” debuted at No. 1 on Billboard’s Top 200 Chart and has already spawned the multiweek No. 1 smash hits “Need You Now,” “American Honey” and “Our Kind Of Love.”

Lady Antebellum first took country music by storm in 2008 with the release of its self-titled platinum certified debut album, which generated the hits “Love Don’t Live Here,” “Lookin’ for a Good Time” and the No. 1 hit “I Run to You.”

Also performing at the Labor Day concert will be Sunny Sweeney. Gates will open at 5 p.m., with the show starting at 7 o’clock. Tickets are $37.75, $51.75 or $61.75, plus processing fees.
