Concerts, Documentaries, Video Comps, the works. Stuff I love and others I want to see. These just came to mind, I'm sure there are plenty I'm missing. Recommend/remind me of all the goodness.
Tried to keep it it Artist/Band specific but a few on collecting and instruments may have snuck in.
No musicals obviously. Though interpretive rock operas ala 1/2 Mensch are sort of their own thing.
