Chicago, the legendary Rock & Roll Hall of Fame band with more than 100 million albums sold worldwide, are captured in this 2½ hour event recorded this past November at Ovation Hall at the Ocean Casino Resort in Atlantic City, NJ in front of a live audience of 10,000 fans over two nights. The film, produced by Award Winning Producer Barry Summers as part of the critically acclaimed 'Decades Rock Live' concert series, features the band who play songs from the album, including some never-before-performed songs as well as 'unplugged' versions of some of Chicago's classic tunes. Joined by special guests Robin Thicke, Chris Daughtry, Steve Vai, VoicePlay, Judith Hill, Robert Randolph and Christone 'Kingfish' Ingram, each performance is visualized in vibrant video and animation. To celebrate the 55th anniversary of their double-Platinum debut album, 'Chicago Transit Authority', the band plays songs from the album, their biggest hits, and 'unplugged' a cappella arrangements of some of Chicago's classic tunes captured in an emotionally moving centerpiece, with each visualized in all original full-length animations shown against an an amazing custom LED backdrop.
