JON ANDERSON is undoubtedly one of the most recognizable voices in progressive rock as the lead vocalist and creative force behind Yes. Anderson was the author and a major creative influence behind the series of epics produced by Yes and his role in creating such complex pieces as Close to the Edge, Awaken, and especially The Gates of Delirium was central to the band's success. Additionally, Anderson co-authored the group's biggest hits, including I've Seen All Good People, Roundabout, and Owner Of A Lonely Heart.
