Jam band O.A.R. has extended plans for its current tour, adding a new leg of concert dates for the United States in early fall. The second leg of the national tour begins September 15 at Ruth Eckerd Hall in Clearwater, FL, and wraps October 9 at Fox Theater in Oakland, CA.

The 15-date addendum focuses primarily on Gulf Coast and West Coast markets, with a few forays into other regions of the United States. Booked performances include September 20 at the House of Blues in New Orleans, LA; September 25 at PNC Park in Pittsburgh, PA; and October 6 at Paramount Theatre in Seattle, WA.

The first public onsales for the tour begin over the July 16-18 weekend. Ticket face values range from just under $30 up to $40 for most of the concerts facing upcoming onsales, according to current listings on Ticketmaster.com.

O.A.R.’s summer tour leg launched July 8 in Indianapolis, following a special July 1-2 stint at Summerfest in Milwaukee. Although only a couple weeks old, the trek has not been without incident. A planned July 13 at Sokol Auditorium in Omaha, NE, was cancelled last night after inclement weather disrupted the group’s travel plans.

“So sorry about the show tonight Omaha. It was out of our hands and in Mother Natures [sic]. We promise to make it up to you,” the band wrote on Twitter. “Stand by for refund and rescheduling information. Due to bad weather and flight cancellations a few us weren’t able to get to Omaha in time. Our deepest apologies to everyone.”

The venture continues July 15 at Red Rocks Amphitheatre in Morrison, CO, and takes a brief break after an August 15 show at the Amphitheater at Encore Park in Alpharetta, GA.

The band is preparing for the release of its next studio album, an as of yet untitled effort that O.A.R. plans to drop in early 2011, according to a recent interview with Billboard.

“Sonically it’s a lot like [O.A.R.’s] first records,” frontman Marc Roberge said in the report. “We want to people to feel good. Everyone’s kind of been dim lately — me included. It’s been a darker time. Now it’s time to put that down and look more positively towards the future.”

Earlier this year, the group released the two-disc live album, “Rain or Shine,” which had been recorded over the course of two nights at Chicago’s Charter One Pavilion during the This Town Tour in 2009. As a nod to last summer’s recorded performances, the current tour returned to the same Windy City venue for a July 9-10 stand.
