Well I've pre-ordered this on the basis that Pearl Jam are one of the greatest rock bands of my generation and that Ten was such an important album that a re-mastered version was certainly worth the investment. In addition, I don't have unplugged, so a DVD of this is certainly worth the pennies. However, having taken a peek at the Pearl Jam website last night, I saw a link to play some of the songs of the collection and found a version of Once which is not only re-mastered but completely re-mixed by Brendan O'Brien! I really must say, if all bands who re-issued their records took the time to completely overhaul the songs to give existing fans a new take on the songs as well as a re-master of the original recordings then I'd invest more! If you haven't already heard the version of Once on the PJ website then listen to it immediately!!! It'll rock your socks off!!!!
