Some really nice individual shocked me today and sent me all 4 Boston Elevation shows! I'm thrilled to say the least heh :-D. He told me that these were Mellow Recordings versions and I have no idea what that means. I figure I'd ask everyone here since I've looked at a couple sites with not much luck. If anyone knows the recording info on these I'd appreciate it. I haven't traded much U2 to know what he was talking about so I'd love a little help. Thanks!
