3. Deep Purple - Made in Japan (originally released: 1972). The reissue has the encores - "Speed King," "Black Night" and "Lucille" - tucked away on a separate disc. It's worth having for those songs alone, but it's also an interesting because it's indicative of a subtle shift of how rock was already becoming a series of niche markets - in subsequent years, Made In Japan was often referred as the Greatest Heavy Metal Album of All Time as opposed to the Greatest Rock and Roll Album of all time.

4. Ten Years After - Recorded Live (originally released: 1973). As far as I know this is just a simple transfer to CD from LP, available as a 2 CD set or a slightly edited single. I still like it better than the Fillmore set that surfaced a few years back.

5. Mott the Hoople - Live (originally released: 1974). Most people know that this album was a cut and paste affair from the start, so restoring (most) of the two sets, one on each disc, was a welcome for most fans. Yep, a must have - a document that shows even without the presence of original Hooplers Mick Ralphs and Verden Allen, the band could still lay a lickin' on most so-called rock and roll bands of the mid-70s.

6. Led Zeppelin - Soundtrack from The Song Remains the Same (originally released: 1976). One of the biggest disappointments in the history of classic rock albums, this recent restoration is the finest example of how a mix can make or break an album. Although the band and most fans agree it was a pretty mediocre performance, the recent remix just shows that even when they were mediocre, Zeppelin could still tap into the fundamental mystique that got them to the top.

Although still not as good as the posthumous live release How the West was Won, the reissued soundtrack to The Song Remains the Same captures enough of the band's magic and power to finally allow it status as an essential part of their recorded canon.
