As part of a thank you to a friend's dad for letting us stay at his beach house, I was planning on giving the guy some good concert films. He just installed a fantastic projection theater into that house and is an audiophile. He is into concert films and so I figured I'd pick up some discs. Fortunately for him, he has money to buy whatever he wants and already has pretty much everything on DVD, but I think his Blu Ray concert selection is slim. I figured I'd pick up Stop Making Sense and The Last Waltz, but didn't know if there is any improvement over the DVD format with these since he already has the DVDs. Any other suggestions would be appreciated. I was also going to burn him copies of the phish Hampton run, so if there are other non-commercial videos which are pretty good, those suggestions might be helpful also.
