"Donjr-I don't have these recordings, which is the better recording regarding sound quality? Are there any bootleg recordings you recommend?"
I listened to Physical Graffiti on Classic the other night. It is not audiophile quality, but it is very good. I don't have a standard pressing to compare with, but I like the Classics very much. I think the Stairway they did on 45RPM, is exceptional. Too bad Classic didn't press more of that 45 RPM big box. Judging from my Stairway, that is the way I would want to hear all their records.
