Oh man. I've spent a full day listening to Rush on CD. More than once.Well, I'd say that rather depends on how you define "performance". Is a live performance the same as a recorded one? I wouldn't say so. I'd never sit and do nothing but listen to a single band's music on CD for hours on end. But, I'd certainly go to a concert by that band and listen for a few hours. Heck, live music, frequently, isn't even as good as what you get on a CD, but, I'll still go see a live gig over just sitting in a room and listening to the same songs.
