Wither Jimmy Page?

Page is/was one of the most innovative blues/rock guitar ARTISTS with Zeppelin and ws an irreplaceable part of that group.

Emphasis on ARTIST. He did things with Zeppelin that no body else thought of or did at the time, as did the group as a whole. Their's is a very unique body of work.

That is what Jimmy Page will always be known for. What else can he do now that won't pale in comparison?

the pact with the devil ran out in 1976 ;-)

seriously, page used to have three or four classic riffs in every zep song

by the firm, cloverdale, etc - there wasn't any magic
believe me, he was trying

his live playing with P/P was inspired
he really needs a good muse

he has faded when others kept on producing

Who is still doing inspired work after their former brilliant work while using. This isn't to say you don't see flashes of the old brilliance but by and large, there's a period and after everything's cleaned up... ther goes the music.
Who is not?
Paul Westerburg
Paul McCartney
Eric Clapton
Jimmy Page
David Gilmour
et. al.

Lou Reed

I'm not at all sure I'd put Paul Westerberg on that list.
