Coolest thing about the Internets

I've got a brother in law that is an unrepentant Dead Head. He vaguely (but fondly) remembers shows that he went to during his Penn State days. How cool is it that now, almost 30 years later, you can visit a website and download those shows, burn them to a CD and have them in your collection?

I think that this is the first show I ever saw, at the Spectrum, my sophomore year in high school, with George Corrigan. I remember Terrapin into Playin in the Band, and US Blues as an encore. I think.
