The Eagles have unveiled "How Long," the first single from "Long Road Out of Eden," their first new studio album in 28 years.

The cut was delivered today (Aug. 16) to U.S. radio outlets and will be available exclusively via walmart.com, samsclub.com and eaglesband.com starting Monday. A video for the track, shot recently in Los Angeles, premieres the same day on CMT.

"Long Road Out of Eden," which will also only be available at Wal-Mart, Sam's Club and via the band's Web site, is due in October. Guitarist Joe Walsh recently told Billboard.com the Eagles will tour extensively next year in support of the project.

"I didn't want us to be too ballad-y" on the album, Walsh said. "We need some stuff we can play live, so I made sure there was that element in the record."

The Eagles will be back on stage in October during a six-night stand with the Dixie Chicks as part of the opening of the new Nokia Theatre L.A. Live in downtown Los Angeles.
