If there is a guitar involved, it's Joe ................
Elton John
I've always thought he was very talented as a pianist, Brian.
Now, as far as guitarists go, there are a bunch but the two that have impressed me the most are Joe Satriani followed by Yngwie Malmsteen.
Absolutely.I think it's to hard to pick just one musician in this category since it all depends on what instrument they play.
Little Roy Lewis.
He plays several instruments in this clip, but my favorite part is when he takes over the bass part at 3:31...
YouTube- The Lewis Family (1993) - Good Time Get Together
Runners up would be Chet Atkins and Jerry Reed.
These guys can play a range of music, and in Roy's case, instruments. Roy is definitely under appreciated.
Chet Atkins
Roy Clark
You wanna drum, and have an excellent big band...
Buddy Rich
Dang, I miss this guy; he would have blown all the guitarist away...
Stevie Ray Vaughn
For vocalist, Linda Rondstadt. Rock, country, jazz, bluegrass, Spanish, all done very well.
Amazing violinist; rock and classical
Lucia Micarelli
Drummer, definitely the Jazz influenced
Buddy Rich
Steve Smith
