In late August, All Time Low performed its biggest and longest U.S. headliner concert in its home state, at Merriweather Post Pavilion. Now, big-time fans will be able to watch the band light up the stage with “Forever: Live From Maryland,” billed as a “live concert stream,” released Thursday.

“This is a celebration of twenty years of All Time Low and the community built up around us,” said lead singer Alex Gaskarth, in an online statement announcing the release. “If you weren’t able to be there in person, you can still be a part of the incredible moment.”

A 33-second teaser video for the concert stream, which will be available for purchase via On Air, a streaming service for concerts, shows an energetic crowd and All Time Low bandmates Gaskarth, Zack Merrick, Rian Dawson and Jack Barakat rocking out on stage with flame effects.

The band formed in 2003 when the musicians were still attending Baltimore County high schools, and has since released multiple gold and platinum-certified albums and singles.

Their Aug. 24 show at Merriweather came on the heels of a new album of re-recorded hits, including “Dear Maria, Count Me In” and “Six Feet Under The Stars,” titled “The Forever Sessions – Vol. 1.” The album was released on Aug. 23 via the band’s new record label, Basement Noise Records, launched in partnership with Photo Finish Records, according to a news release.

Before a concert at the Maryland State Fair last year, Gaskarth told The Baltimore Sun that the band’s hometown shows have a “special energy.”

“Our main vessel for our music has been our live shows, throughout our entire career,” he said. “We write our songs so that we can go play ‘em on a stage.”
