PORTLAND — My Morning Jacket, Josh Ritter & The Royal City Band, Guster, and Michael Franti & Spearhead will be the first pop music acts to play the historic State Theatre when it reopens this fall after a four-year closure.

The theater’s grand reopening line-up was announced this morning by Lauren Wayne, theater general manager. The specific dates and ticket prices are: My Morning Jacket on Oct. 15, $40.50 ; Josh Ritter & The Royal City Band, with Low Anthem, on Oct. 22, $20 and $25; Guster on Oct. 27, $27.50; and Michael Franti & Spearhead on Nov. 6, $30.

Tickets for all shows will go on sale Friday, July 30, at 10 a.m. at the State Theatre website, or at the Cumberland County Civic Center box office, Spring and Center streets.

Also, to let a wide variety of people see the reopened theater, there’ll be an open house at the State on Oct. 17, with free performances from 1 p.m. to 9 p.m.

The line-up will include local artists Darien Brahms, Jacob and the House of Fire, Brenda, Sidecar Radio, Atomik, and others.

“We’re looking forward to bringing in all types and genres of musicians in order to appeal to a wide audience. We want this theater to be accessible and welcoming to as many people as possible,” said Wayne, who has been a concert booker and active member of Portland’s music scene for years.

“It’s exciting to be part of a project that will eventually help make a unique and amazing connection between artists and musicians and their audience, and to be able to witness this kind of connection happen at such a historic and beautiful venue makes it even more exciting.”

When Guster plays, it will be like having a local band there, since band member Adam Gardner lives in Portland.

The State Theatre, in the heart of the city’s arts district near Congress Square on Congress Street, was built in 1929 as a movie theater. It eventually became a porn theater and then in the early 1990s was converted into a performing arts venue. It was run by several groups at various times until it closed in 2006.

This year, New York City promoters The Bowery Presents and local promoter Alex Crothers took over. The new management’s plans include refurbishing the stage, installing new seating, and installing new sound and lighting equipment. The theater is expected to have a capacity of about 1,450.

Wayne said more shows at the reopened State will be announced soon.
