These guys have tons of live performance Cds by a wide selection of bands. Some have mediocre quality but where else will you find 20+ Deep Purple live shows from the 70's ? They also have a nice selection of oddball music magazines from all eras. They also have a bunch of vinyl (old and used) that covers most of the rock era. An interesting place to shop but be prepared for some sticker shock when you see what they charge for some of the live material.
