This six-CD box set is quite cool. Each of the shows has a bit different flavor. The first one (Argentina) is the most pure prog set of the bunch. The middle one (Osaka) leans a bit more toward an almost metallic AOR. The final show (Tokyo) lands somewhere in between. There is a lot of duplication of songs across the three shows, but there are some pieces that separate it. Even though we get a number of versions of various cuts, though, they are different enough in performance to make it work. The first two concerts are captured with excellent audio quality. The last one is a bit less than perfect, but still acceptable. I've reviewed each of these albums individually in addition to covering the box set. For the sake of consistency this review and those are essentially the same.
