I'm pretty sure the wife & I caught the 75-76 tour when they came through New Orleans. Yes, it was unbelievable. Easily one of the best live show I've ever seem.
First time I saw Eric live was about 1975 - he was touring with Carlos Santana. They did a set together to close out the show, it was unbelievable . He is better than anyone alive, he claims Robert Johnson could do licks that he still can't figure out. If so Robert me be the greatest ever, Eric at #2. Rolling Stone mag doesn't even recognize Johnson making them a waste of paper.
