America is releasing a new live album, America – Live From the Hollywood Bowl 1975, on September 6. The show was recorded on August 3, 1975, at the legendary Los Angeles venue, with the Beatles’ celebrated producer George Martin conducting a symphony orchestra backing the band. Martin produced seven consecutive albums for America, including their multi-platinum collection, History: America’s Greatest Hits. The tapes for the Hollywood Bowl show have never been heard before, and the recording was recently restored and remastered for the release.

“We had developed a great partnership with Sir George Martin the year before with our first project together in London, the album Holiday,” America’s Dewey Bunnell said in a press release. “The live performance had evolved into a strong show, and we toured a lot that year playing large sold-out venues. George was involved from the beginning of the planning, and it was decided that he would conduct a symphony that would include him performing first, and he would then conduct behind us during our show.” (Ultimate Classic Rock)
