I've only been around forums like this for about a year, and I've only been a Zeppelin fan for about 2 so I'm not the most knowledgeable on stuff like this. Sorry if this is common knowledge or whatever. My question is pretty simple: Is there any possibility there are more multi track recordings of the group than we know? For instance, how long did we know about the NA '72 multi-tracks or the Southampton '73 multi-track before they saw some type of release? Was the Zeppelin fanbase in shock when Page announced they'd be using these shows, or was it expected these shows would eventually be heard in this quality? I believe I saw a list on this site once of all multi-tracked shows that went something like this: 10/17/69 - Carnegie Hall (Although from what I've read since it seems as if there's nothing here) 1/9/70 - Royal Albert Hall: Partially released on the Led Zeppelin DVD 9/23/71 - Tokyo 9/24/71 - Tokyo 9/28/71 - Osaka 9/29/71 - Osaka 6/25/72 - L.A. Forum: Released on How the West Was Won 6/27/72 - Long Beach: Released on How the West Was Won 1/23/73 - Southampton: Leaked and widely available 7/23/73 - Baltimore: I've read in a few places that this one (and the following night) was rumored to have been multi-tracked. 7/24/73 - Pittsburgh 7/27/73 - Madison Square Garden: Released on The Song remains the Same soundtrack 7/28/73 - Madison Square Garden: Released on The Song remains the Same soundtrack 7/29/73 - Madison Square Garden: Released on The Song remains the Same soundtrack 5/17/75 - Earl's Court: This and the following night people seem tentative on whether they were recorded or not. Do we have a definitive answer on this? 5/18/75 - Earl's Court 5/23/75 - Earl's Court: Partially released on the Led Zeppelin DVD (I think? I believe I've heard people hesitant on whether we've seen film from this show or not. I'm not exactly huge on the EC shows so I've never looked into it) 5/24/75 - Earl's Court: Partially released on the Led Zeppelin DVD 5/25/75 - Earl's Court: Partially released on the Led Zeppelin DVD 8/4/79 - Knebworth Festival: Partially released on the Led Zeppelin DVD 8/11/79 - Knebworth Festival: Partially released on the Led Zeppelin DVD Have any of these gigs I listed more tentatively been proven true or false that they were multi-tracked? And how long did it take the fanbase to glean the info on these performances to determine this? Again, I'm asking this simply because I wonder if it's possible that there are multi-tracked performances we have no clue about.
