Yeah actually they have 2 dvds, La Piazza Del Campo(that features their original violinist Mauro Pagani), and the live in Japan DVD. Wich in terms of sound and songs i prefer the Japan one..La Piazza del Campo is awesome, but Japan DVD is more complete , has guitar+piano solos...and songs like Maestro Della Voce that are way better live than the studio version...you SHOULD get Japan dvd. I havent seen something as cool as that concert.
I saw Yes Anniversary and i was so bored with S.Howe soloing and annoying sounds that i turned the DVD player off. Bunch of people told me "they are old"....Premiata are also old but playing better than 30 years ago..."old" is not an excuse.
Stay Classy
