What is your favorite guitar solo of all time?

Walter Rossi!
Great suggestion. Haven't listened to him in years
Has a unique guitar voice and deserves mention in this thread

Soundgasm,

The short solo in service to a great pop song is almost a separate subject unto itself. I'd also choose the Rundgren example you cite, and I'd add Dave Davies' (Kinks) solo from "I'm Not Like Everybody Else", Dave Edmunds'(Rockpile) solo on "So It Goes", and Terry Kath's (Chicago) solo on "25 or 6 to 4" to that list.

PS two more from my hero, Lindsey Buckingham:

"Go Your Own Way" from Live @ Bass Performance Hall
"(This is The) Time" from Out of the Cradle

Martykl,

How could I have forgotten Terry Kath?

I have a lot of favorite solos but the most hair raising is the original master recording Mobile Fidelity Utradisc II Muddy Waters Folk Singer. The dynamics from low to high are definitely hair raising.

Leslie West, "Don't Look Around" simply smokes, he is my all time favorite geetar man
