Fortunately there are dozens of great scorching guitar moments available for hungry consumers. Can't pick a best, but McLaughlin Inner Mounting Flame is *#*&**!!! brilliant. "Purpose of When" from his Devotion record kills too. Sonny Sharrock "Dick Dogs", Reeves Gabrels "Heavens In Here", Ollie Halsall "Money Bag", Peter Wolbrandt "Holiday in Martenhorn" John Etheridge on "Saturation Point", Zappa "Muffin Man", Michael Karoli "Vernal Equinox"... Checking out David Fiuczynski, David Torn, Toto Blanke (Spider Dance) and Ron Thal (Bumblefoot) should pay off too. There's a not too bad Banyan "Maggotbrain" clip on Youtube where Nels Cline tears it up pretty good. Gotta agree there was only one J. H. the Ax Generich stuff on early Guru Guru records nails the LSD Hendrix thing.
Best guitar explosion of all time
My vote is for Jimi's Voodoo Chile - a Slight Return! No one has come close to his majic on that recording. I am a big Jeff Beck, Jimmy Page, Eric Clapton fan and everything they have done falls short. Not for emotional involvement, or technical virtuousity, but for the finality of the perfect guitar moment. Jimi hit it on the mark - and then some!
