After racking up sell-outs in markets across the nation, Adam Lambert’s summer concert plans have expanded to fill the end of the season. The former “American Idol” runner-up’s Glam Nation Tour itinerary has taken on more than two dozen dates since onsales started in mid- to late May, pushing the full concert count near the 70-date marker.

Some of the newer additions to the calendar include gigs on July 7 at Ryman Auditorium in Nashville, TN; August 1 at The Marquee in Tempe, AZ; August 17 at Lupo’s Heartbreak Hotel in Providence, RI; August 31 at Clowes Memorial Hall in Indianapolis, IN; and September 14 at Woodruff Arts Center in Atlanta, GA.

The Glam Nation Tour officially launched in early June and is already nearly ten dates into its run. Lambert’s tour, which features support from Orianthi and fellow “Idol” alum Allison Iraheta, continues later this week with a June 17 concert at Horseshoe Casino in Hammond, IN.

Public onsales for the newest tour dates are scheduled to start over the June 18-19 weekend, though many earlier dates of the tour are already available. Most ticket face values are set around $30 to $40, but prices in some markets reach up to the $60 range, according to Ticketmaster.com.

Lambert’s summer tour has proved to be a sell-out success in several markets. Among the numerous sold-out dates are concerts on June 27 at the Rams Head Live! in Baltimore, MD; July 6 at the Tennessee Theatre in Knoxville, TN; and August 8 at The Pageant in St. Louis, MO, according to venue reports.

The Glam Nation Tour has also proved its selling power in larger U.S. markets. Most notably, a June 22 sell-out at the Nokia Theatre in New York City prompted the singer to add a June 23 show at the venue, which sold out just as quickly. Out on the West Coast, a sold-out July 23 gig at the Warfield Theatre in San Francisco led to the addition of a second sold-out date in the market — July 25.

In a recent interview with USA Today, Lambert credited his touring success to the connection he’s made with audiences and the dedication of the fans who have followed him since the 2009 season of “American Idol.”

“Especially with this tour, I’ve honed in on the spiritual quality of the performance. There’s something that happens between you and your audience when you’re really connected,” Lambert said. “My fans have been so dedicated and passionate about what I do. This show was really built for the fans.”
