Some of my favorite concert experiences have been (relatively) no-name artists playing small clubs trying to build a following. It doesn't happen often, but every now and then my son and I have been seated at a table right beside the stage where some mind-blowing musicians we've never heard of are just tearing it up! Maybe 20 patrons in the whole club! Or not!

And the cool thing about those venues is that between sets and after the gig, these guys will talk to the audience and even show you their gear and explain how they get their signature sound.

Also at big venues like Merlefest where they book enough artists to fill 11 stages for 4 days... I have consistently been most impressed by the young artists and semi-pros who are not the headliners. Lots of good bands from Canada (don't ask for names... liking their music doesn't mean I remember their names) and some from Ireland.

As far as memorable rock acts: Seeing Led Zeppelin at the Pittsburgh Civic Arena in '69 (or '70?) was memorable.

Always wanted to see Deep Purple, but it never happened. One of my later bands had an organist with a B3 who loved Jon Lord, so I got to learn all those interesting Ritchie Blackmore guitar solos.
