How do you make a perfect album even more perfect? In the case of Van Morrison’s seminal 1970 neo-rock Caledonian masterpiece Moondance, you compile a 70-track deluxe edition that includes three discs of sessions, outtakes, and alternate mixes, in addition to a separate Blu-ray Audio disc with a long-lost surround sound mix done by one of the album’s original engineers. Yes, as any good Van the Man fan knows, it’s too late to stop now.
