AUGUSTA – Phish’s upcoming concert at the Augusta Civic Center sold out in 20 minutes after tickets went on sale to the public.

The renowned Vermont-based jam band comes to the city-owned auditorium Oct. 19.

A few of the band’s more devoted fans camped on the front lawn of the civic center the night prior to the Sept. 10 public sale date, said Dana Colwill, director of the civic center.

Seven thousand people are expected to attend the show.

“Our capacity is normally 8,000, but they have a large mix area (reserved for sound-processing equipment), and these Phish fans like to dance around in circles and need more room than a typical festival-style concert,” Colwill said.

Colwill said the promoter for Phish contacted the civic center about two months ago, looking for dates and saying the band wanted to play a new venue.

More than half of the tickets were sold through Phish.com before the public sale date.

Colwill said the civic center had an allotment of about 2,700 tickets. They were sold for $60 each at the civic center and through Ticketmaster.

“This will bring a lot of money into Augusta for our local hotels, restaurants, retail stores and gas stations,” Colwill said.

Last year, Phish played the Cumberland County Civic Center in Portland — a show that sold out in just two minutes.

As of Friday, all but two shows on Phish’s 14-date fall tour were sold out.

Tickets still remained for the Oct. 26 concert at the Verizon Wireless Arena in Manchester, N.H., and the Oct. 15 show at the South Charleston Coliseum in South Carolina, according to Phish.com.

For the first time, included in the ticket price for each show is a free MP3 download of a recording of the entire concert, redeemable at LivePhish.com, according to the band’s website.
