Two-for-one available on AOL site.

Clear Channel Music Group is teaming with the Backstreet Boys and AOL Music to offer two-for-one tickets for the group's upcoming summer amphitheater tour.

Beginning June 10, fans who visit aolcityguide.com and buy two reserved seats for the band's summer dates will get two free lawn or mezzanine seats to the same show. No facility fees or ticket surcharges will be applied to the free tickets.

The tour, which is also presented by AOLMusic.com, begins July 22 at the Sound Advice Amphitheatre in West Palm Beach, Fla., and runs through Sept. 2 at the Clark County Amphitheatre in Portland, Ore. The ticket offer only applies to the tour's Clear Channel venues.

The free ticket offer runs through June 24. Regular tickets for most dates go on sale June 17.

"When we sat with the Backstreet Boys' management, our overriding objective was to figure out a way to reward their fans because it's been so long since they've been on tour," says Faisel Durrani, executive VP of marketing for CCMG. "The initiative was an idea that [their manager] Johnny Wright had. It wasn't sitting around with the accountants and figuring out how this affects our gross."

AOL will serve as the campaign's exclusive media driver.

This announcement comes a week after CCMG debuted its new lawn seating pricing plan, and started allowing lawn patrons to bring food, blankets and chairs into amphitheaters again. Millions have also been invested on capital improvements for CCMG amphitheaters. Durrani notes that this ticket offer is a "continuation of that campaign."

The Backstreet Boys' first new album in about five years, "Never Gone," debuts June 14 on Jive Records. The quintet is expected to launch a stadium tour next year.
