The November 2016 Sound and Vision has a page on the Quadio Chicago Box, where Mike Mettler interviews Lee Loughnane about the quad Chicago mixes. If you don't have the magazine you can read the interview on their website. Also on the site is another Mike Mettler interview, this one with Rick Wakeman, where he talks about his quad albums being released again, and Steven Wilson's work with the Yes catalog!
