Andrew Duch at the Headstash site has written a thought provoking article about how technology will change the Jam Band scene.
Duch sees a decline in "organic" roots rock music like the jam band genre, in favor of electronica and DJ based music. He also considers the implications of RFID wristbands and smartphone apps to allow cashless festivals and friend finding features. Interactive shows and enhanced couch tours also could be part of the future if bands embrace and facilitate the technology, like audience taping, instead of fighting it.
Food for thought.
