OK, I know this is a bit vague but it's all i have, pre 1984 tune, from a live concert,it sounds like it could be Carlos Santana to give you an idea of the sound. I was given a 'mixed bag' tape with no credits and one tune is just a guitar player, no lyrics to speak of only the player says "Shh, Relax, Relax" at the start and then goes into this beautiful (electric) guitar solo, anyone have a clue who this could be? i have been at this since i lost the tape in 1985 and would be eternally grateful for any help, thank-you, T.R
