If anyone is interested, I made a Led Zeppelin compilation in iTunes that covers their 1968-1973 peak period. I placed all outtakes and live tracks in chronological order.
I can put it on my google drive.
Please do.
I came across an 18 CD set named Studio Magik. It contains mostly demos and outtakes, but the real gems are:
CD1 contains Moby Dick as two separate tracks. Intro & outro on one, the entire uneditied drum solo on the other. Jimmy Page is a genius in the studio and knew exactly which part of the drum solo to put on the album mix and which parts to edit out. From these tracks, you can make your own longer version.
CD2 is dedicated to Whole Lotta Love. It contains eight separate raw tracks (2 guitar, bass, 3 drum, 2 vocal). There are four mixdowns, all of which are a little different from the album mix.
CD3 is dedicated to What Is and What Should Never Be. It contains eight separate raw tracks (guitar, bass, 2 drum, 3 vocal, guitar + vocal). There are three mixdowns, all of which are a little different from the album mix.
CD4 is dedicated to Heartbreaker. It contains eight separate tracks (2 guitar, bass, 2 drum, guitar + bass + drum, vocal, guitar + vocal). There are two mixdowns, both of which are a little different from the album mix.
CD5 is dedicated to Ramble On. It contains eight separate tracks (3 guitar, bass, 2 drum, vocal, guitar + vocal). There are four mixdowns, all of which are a little different from the album mix.
These are all FLAC format. I can put them on GD.
