After more than 100 performances worldwide and numerous revisions, the new recording represents Jon's definitive version of the masterpiece, which in 1969 pointed his career in a new direction and laid the foundation for an astounding musical reputation and career. Guests and soloists on the new recording include Bruce Dickinson, Joe Bonamassa and Steve Morse along with Jon's 'house singers' Steve Balsamo and Kasia Laska. It was recorded at Liverpool's Philharmonic Hall by Abbey Road Studio's crew. The recording was conducted by Paul Mann, whose in-depth experience with the piece includes conducting its 30th anniversary resurrection at London's Royal Albert Hall in 1999 and the ensuing world tour with Deep Purple. The new release will be accompanied by a specially filmed documentary.
