I saw somehing similar this past summer when bob was at ALL GOOD- It all goes like this...
First off, i don't really enjoy yonder mountain as much as say hot buttered rum, or nickel creek, so i left during there set to go take some bong rips at my site and play my own guitar. on my way back i heard the sound of bobby's guitar at the ropadope (second) stage where there is always sometype of cool improve thig going on. There was the ratdog core of Bob, Jay, Robin , and Jeff, but then there were a bunch of other musician that did not recognize. They jammed for about an hour or so when all of a sudden two dudes came up on stage and started rapping. I must say i was impressed, it was fun, and it seemed all improvisational. However, if i was at a specific ratdog show and instead of playing an actual song, bob just had some mediocre rapper come on stage, i would be pissed. That is too bad that shows encore got ruined, but ho hum.
Would you please remove your rubber duckie from my guacamole...Thanks!
