1. The remastered version of The Joshua Tree sounds way better (and louder) than previous editions on CD.
2. The Bonus CD: it's great to have ALL the remastered b-sides from the Joshua Tree singles on one CD (The Best of U2 1980-1990 only featured a selection of these tracks) + some of the outtakes, although obviously unfinished, give an idea of various directions the band could have taken with this album. A special mention goes to "Rise Up", which sounds almost exactly like Edge's and Sinéad O'Connor's "Heroïne" from '86. Also included are both versions of "Silver and Gold", one by U2 and the other by Bono with Keith Richards and Ron Wood of the Rolling Stones.
3. The DVD contains a full concert from the beginning of the Joshua Tree tour. Where the Rattle and Hum film used footage from later in the tour, when the band was not only getting better at playing the new songs, but had also already cut some of them out of the set list, here they were still road testing most of the songs from the album. Even the hit songs were not classics yet, so U2 doesn't even bother to play "Where the Streets Have no Name", which is something they probably couldn't get away with today. They also weren't performing as many covers as they would later in the tour, which leaves more room in the setlist for songs from the first four albums.Also included is a documentary featuring footage from the first leg of the American tour, including photo shoots with Anton Corbijn, the band performing country songs in small clubs and even shopping for cowboy boots. Interesting to watch because U2 were so much less self conscious than when filming Rattle and Hum. This footage shows U2's less serious side, which makes this DVD an essential complement to Rattle and Hum.
