I treated myself to the newly released Led Zeppelin I, II, III High Res downloads from HDTracks this weekend. Jimmy Page did a real good job re-mastering this set! I have a box set that I bought about 10 years ago. I was never pleased with any of the recordings. Consequently they never got played much. I'm so happy that I can listen to these HiRes versions in all their glory. It feels like I'm in the studio back in 1969. Oh yeah and they have a bunch of alternate mixes, "rough mixes", live concert tapes and some other goodies that are worth the upgrade by themselves. #Thumbs up
