What is your favorite guitar solo of all time?

It's a difficult question,maybe your top 2 or 3 that year after year blow you away and raise the hair on your head and move your soul inside.
One? no way..
Jeff Beck, Because We Ended as Lovers
Christopher Parkening, Laudate from Mozart Vespers
Terry Kath, 25 or 6 to 4
-I agree with Audiofeil on Hendrix's Voodoo Child,although Stevie Ray's version from the box set is mighty fine.
-Blowin' Free by Wishbone Ash
-Europa by Santana
-One Way Out- Allman Bros. Eat a Peach version
-Sweet Jane- Lou Reed Rock and Roll Animal version
-Cruise Control Dixie Dregs
-Because we ended as lovers-Jeff Beck
-anything by Danny Gatton

As far as acoustic goes, anything by Michael Hedges, Tommy Emmanuel, and as mentioned above, "Blue Sky" is the reason God invented the guitar.
Ted Nugent....Stranglehold is one that comes to mind. Sooo many others though....
Steely Dan - Show Biz Kids (Countdown to Ecstasy)
Joe Satriani - Circles (Surfing with the Alien)
Wishbone Ash - Sometime World (Argus)

There are many more that have caused me to horripilate over the years these three...
Calvary Cross live by Richard Thompson
Harlem Nocturne. Danny Gatton
