Country music’s Kenny Chesney is coming to Maine.

The singer who sold out Foxboro’s Gillette Stadium in only eight minutes last November will headline a concert April 7 at Cumberland County Civic Center in Portland.

“It’s dramatic,” said Steve Crane, the general manager of the Portland arena. “To play a little building like this is extraordinary.”

Some details of the concert, including when the tickets will go on sale and how much they’ll cost, are still uncertain, Crane said.

Crane doesn’t even know how many tickets will be available for sale, he said. Chesney’s rock-style production might be so big that the number of seats could be as few as 6,200, Crane said.

He expects Chesney to be careful not to price the concert so high that only rich people can afford to attend, he said.

“The great thing about country music artists is that they do work all the time to maintain their fan base,” he said. “They think long term.”

Crane conservatively labeled the show “a likely sellout.” After all, Chesney has sold out the Patriots stadium six times.

He has also performed at the Civic Center twice before, in April 2002 and again in August 2004.

Since then, he has become a dominant force, particularly in his live shows. In 2009, he became the first live performer in the United States to sell more than one million concert tickets for eight consecutive years. Last year, he released his own concert film, “Kenny Chesney: Summer in 3D.”

The movie featured hits such as “She Thinks My Tractor’s Sexy,” “How Forever Feels” and “I Go Back.”

Last fall, Chesney and a video crew were in the tiny Midcoast town of Port Clyde to shoot footage for a music video for his song, “Seven Days A Thousand Times,” according to a report in October by The Bangor Daily News. The ocean theme will be carried in the new Goin’ Coastal tour.

In all, 51 dates have been announced, beginning in West Palm Beach, Fla.

Each show will feature two popular acts: country singer Billy Currington, known for the hit “People are Crazy,” and Uncle Kracker, the hip-hop and pop artist who crossed over as a solo country artist with his single, “Smile.”

However, he and Chesney have worked together before. In 2004, they recorded the duet “When the Sun Goes Down” and hit No. 1 on the country charts.
