Sure he is.. and some obscure country musician like Duane Allman is better than BB King and Eric Clapton when he shouldn't even be on the fucking list.
I can see the Rolling Stone staff sitting doing the list:
"Hey guys, we need to put in some funky names, so the readers think we're different and edgy, and so we're not mainstream. How about... yeah!!! I got one! Duane Allman, anyone heard about him? No? Good. Look up what records he's done, and then put him behind Jimi."
