It's really a shame, and a sad reflection on the state of labels and the music insdustry that The Roots Come Alive 2 or 3 (etc) never materialized. I loved volume 1, but their sound has changed so much and so many times since then! I guess it could be argued that their studio albums have sold less with each new release, but I figure a Live album has the potential to be better than a Roots Studio album.
I also disagree with ?uesto's thinking that a live DVD or CD would take away from their live show. I think it would encourage people to check them out live.
There'll be something eventually I'm sure. I'm just impatient.
