IMO Zeppelin was a good studio band, in the studio they had the discipline to make some classic records. But, I thought they were a terrible live act, really sloppy tedious wankage with little musical substance, all the worst excesses of the 70s rolled into one package. I give them a huge amount of credit for never touring again after Bonham died, to this day they could still regroup and make a fortune. Interestingly it was Bonnie Raitt who called out both LZ and The Rolling Stones for stealing songs from the old blues artists without crediting or paying them. Page also ripped off Bert Jansch when he stole his arrangement of the traditional song "Black Mountain Slide" for the first LZ album without crediting him. Some dicey karma there for sure.
