Atlanta Rhythm Section did ok, nothing special, IMO, certainly not the energy of their prior tours.
The audio at Hudson Gardens could have been a lot better - there were many shouts from the audience about "fire the sounds guys". IMO, bass and treble were maxed out - no creativity or tailoring the audio to the strengths and weaknesses of the band members, the songs or the instruments.
The warm-up band was loud and forgettable (can't even remember who it was that played) - thankfully, they weren't on stage very long.
Black Oak Arkansas, the final band, was a huge disappointment, pretty much just screeching and stomping all over the stage. We, along with probably 2/3rds of the audience left after they started playing. Thought we were going to hear all of their 70's Southern Rock classics - instead, it was new songs that IMHO were just horrible.
