Had to re-read today - was too tired at 2 AM to absorb it all - and Wow ! .... just Wow ! 
So great to read something like that - and so glad I was there so can relate to it.  Hope the great music from those shows makes it's way out eventually.

My favorite comment - - 
 " Burr does more with less and during the manic group-wide, free form drum solo that has become a concert staple, he shows that good drumming involves more than just hitting things "

Yes, yes it does ! ! !  :]
