Well that's the end of our music conversation. You are absolutely 100% entitled not to like certain music... but you've more than shown me that you have absolutely no idea what the hell you are talking about. First of all... DMB fans are ages 25-50
The band has one of the absolute best drummers in the world, Carter Beauford:
One of the best sax players in the biz Jeff Coffin:
A bass player that regularly plays Bach masterpieces on the bass as a solo during shows http://www.youtube.com/watch?v=3Kd2HezxT04
A violin player that can play any style of music and absolutely jams his ass off http://www.youtube.com/watch?v=knCjwOD2dQc
Of course you're probably not going to watch any of this because you don't want to be proved wrong...
But you really are ridiculous.
Best in the world according to who? Take any of those names above and ask anyone on the street who they are and most will have no clue. They are the best in the world according to DMB fans.
Also if I want to listen to jam music, I can go to any bar, coffehouse and restaurant in the world that plays live music. When I was in college I used to go listen to a few jam bands live but after a while I began to realize they all sound the same and stopped going. Saved myself a lot of cover charges and wasted time.
