Daaaamn Marley, that’s like asking “Which is better, the Book of Matthew or the Book of Mark?” (I couldn’t answer that, not having read either in twenty years or so. Maybe not a good example.)
The first concert I ever saw was Jeff Beck (“Blow By Blow” tour, Mahavishnu Orchestra opened) and it made me a music snob. I prefer the later band (Tench, Middleton, Chaman and Powell) to the earlier version, but that may just be familiarity. The Jeff Beck Group seemed more of an ensemble, playing off of each other like a jazz band (or something). Zeppelin seemed more like a backup to the soloist (kind of). Not that anyone in Zeppelin couldn’t play, God knows, more that the song arrangements were structured that way. (Some of them. ow A little bit. ouch I know, I know they were great, I’m just sayin’. OOOW Quit hittin me! )
Still, you can’t deny the Zeppelin influence. I’m the last person in the world to cite sales or popularity, I think they are both meaningless in judging talent, but Zeppelin changed the face of rock music. (Not necessarily for the better, ultimately leading to Huge Shows and Huge Ticket Prices, but still.)
Maybe it comes down to who made more. There are more Zeppelin songs I like than there are Jeff Beck Group songs I like. But I like my favorite JBG song more than my favorite LZ song. (Both change daily, I’m fickle.)
I guess I’m saying, “I abstain.”
Or maybe, “I got to have a sooong”. Definitely Maybe.
