I'm kind of all over the place on LZ, at least on vinyl (since I don't have a CD player in the main system). I have the original LZ 1 that I bought new back in the day- I think it is a Piros, but haven't checked it recently. I also have the Classic Records reissue which plays fine and is less noisy- face it, I started playing my original copy of LZ 1 to death on an AR table with a Shure cartridge circa 1969 and while i took good care of my records as a teen, I continued playing it for decades. I have various copies of LZ II, including an old MoFi, and the desirable 'RL' mastered one. (I also have another copy of LZII that I bought new when it was first released, but have yet to find it- I'm not sure if that copy is an 'RL'). I only bought III recently, and on that, I bought the Classic Records pressing- it sounds very good, better than I expected. I have old miscellaneous copies of IV, HOTH ( I forget which pressing) and that's about it. I really don't listen to the albums after III. My favorite is the first album,musically but it's probably the worst recording of the first three albums.Overall, of the first three albums, the 'RL' of II is the killer, sonically and my copy is hardly mint.
I liked Mothership- it certainly isn't as warm sounding as the Classic Records I and III and I assume came from a digital master. It comes nowhere near the dynamics of the RL version of LZ II. The Mofi II is a better than average sounding LZ record- quiet surfaces, but tweaked in the way that almost all MoFi vinyl was. In the case of LZ II it probably doesn't matter, because there is very little on that album that's pure acoustic stuff anyway- all kinds of phasing tricks, weird stuff- Page manipulating the tapes when he put it together to get the sound he wanted. My bet is III is the most natural sounding of the ones I listen to. I have no idea how this translates to CD. Mothership is pretty good for what it is- I think it's a better job than that recent Beatles boxed set, but that may be a back-handed compliment.
PS: Steve, I know Palladia was playing the movie that had the Madison Square Garden footage a while ago- The Song Remains the Same? It was a weird movie and I found some of the camera work annoying, but hey, I don't know how much footage is available of them in concert. My absolute favorite is that Scandinavian TV show of them when they first broke, playing 4 songs that ultimately appeared on the first album. The whole vibe is very low key, they are not really acting like rock stars, no stage to speak of, and the audience, mostly clean cut teens, are sitting cross-legged if memory serves, on the floor surrounding the band. Page is playing a Telecaster, and is clearly the band leader. They were all young, fresh, and totally kicking ass. And this was really the earliest days of the band as far as I know. That footage is available on a DVD that collects a lot of their stuff and was released in in the mid-2000's?
