Most Influential American Musician of All Time?


Who do you regard as the most influential (i.e., musically, not necessarily commercially) American musician of all time across all genres?

The more I learn about Louis Armstrong, the more I am persuaded that he deserves that honor.

Tvad, Yes David Cassidy is right up there with Bobby Sherman and Frankie Avalon.

All of which, I am sure, broke Annette's heart.....
WAKE UP! Les Paul and Leo Fender. I am surprised nobody here voted on Les Paul and Leo Fender. Hard to imagine rock music without both. Les turned 92 this year and created the most copied sound. No Les; No Jimmy Page or Keith Richards. No Leo; No Hendrix or Clapton.
Bongofury, I didn't know Jimmy Page, Keith Richards and Clapton are American musicians.

from the late 50's on...c'mon it's ELVIS....better yet let's ask our favorite musicians....most of mine said the king...
