For me it was Voodoo Chile by Jimi Hendrix, here's a great version by SRV, the only guy other than buddy guy who could do it justice other than the great man himself:
Here's Buddy Guy's version:
Here's the original song by the great man himself, still makes my hair stand on end!! :
Just trying to think how you would chategorize this type of music? Psychadelic Hardcore Electric Blues?? Seeing Buddy Guy do this song live @ Perth Concert Hall is probably the Music highlight of my life.
What is yours?
