Hey friend. Yes I was there with my son and it was a truly smoking show. I was also at Bristow and that was also an excellent show.
You are "dead" right, they seem to be enjoying playing and are nicely in sync. When they came out of drums/space into Dark Star again, the interplay between Jeff and John was intense and the Cumberland drove hard and never stopped.
The show is up on internet archive for those that are interested.
Going to any of the later shows?
