Please don't compare the musical talent of Pete with Alex Lifeson, with all the respect the grandpa deserves, Alex Lifeson is a way better musician, and yes both played rhythm guitar, at the end they are the only one in their respective bands, so no other choice....Keef....about 40 years ago I would said.....
Jimmy Page, I agree with you on that he never played the same way a song, but have you ever asked him, if is that the way he wants to, maybe he wanted to do it that way, if is like that, you have to agree that he has a lot of talent then, is not easy to get all those new ideas every night, I do believe that he is perfectly capable of reproducing what was done on studio, but maybe he was not 100% satisfied with the job there, and maybe he like to do it better after...there are many variants that we will never know about that, arts are not as simple, as playing a chord here or there, the preference of the musician, is also important, IMO for example Mark Knopfler always leave me with the wish of hearing more in his solos, like incomplete, or mutilate, or extremely simple, same as Becko, but this is the way they play....
