What is your favorite guitar solo of all time?

Joe Satriani's Surfiing with the Alien...whole album is a solo:)

Journey "Of a Lifetime" song "In My Lonely Feeling" before Steve Perry ruined the group.
UFO "Lights Out" song "Love to Love"
Robin Trower "Twice removed From Yesterday" song "Daydream"
Luther Allison "Cherry Red Wine" forgot the album name.

If these songs don't get you playing air guitar, you might be dead.

Carlos Santana, "Blues for Salvador", the 2nd cut "Bella" puts me in a trance.

No question... Hendrix (Band of Gypsys II) "Hear My Train A Comin'. There are a few versions of that song floating around, but on that particular record, it used to blow me away. So much so, that I used to try and time my acid peaks with the main solo (heh, yeah, LSD over 20 years ago).

Still haven't snagged Band of Gypsys on cd an' lost my turntable during an acid trip about 20 years ago... need to get Band of Gypsys again. Also really dig the Little Wing solo from the Jimi Hendrix Concerts disc (1968 live in Winterland)... this one has the coolest LSD warped cowboy underwater sound of any Little Wings I've heard so far.
