Of course it’s an individual criteria of which are famous. The Allman Brothers was my first big show. Robin Trower many times. Jeff Beck in all his variants. David Bowie, Iggy Pop, King Crimson. Keith Richards solo tours, never saw the Stones.

A big part of my life was and is Jazz and Blues artists. Also my hearing can’t handle volume very well. So now the small venues are the best but I still get jams.

I should add that I was at the two Crossroads Guitar Festivals in Chicago. Lots of famous musicians there.

AC/DC Van Halen Iron Maiden KISS Judas Priest Black Sabbath Metallica Slayer Megadeth Scorpions Guns N Roses Aerosmith Def Leppard and many others.

None, they were decades before my time, although I have listened to Queen and the Beatles
