That’s a bit harsh….IMHO the venue is worth the experience. I would compare to Red Rocks in stature. I did it this summer and am glad I did. Of course I paired it with DSO show the night before and got a 60’s treat.
There is no band that has more visual material than the “dead” and that’s what the sphere is all about along with stellar sound. Of course even with selling all the Dead and Co. tickets (scalpers took haircut) the venue still lost its ass. Who would you like to see there?
Above being said, now that I experienced it, I will not go unless I could parlay with DSO again.
