ETA: but if we're comparing, I'd say this was one of the better ones of the post Sheya Mendlowitz era (19+).
I'd like to add one point.
There are many meters by which to measure a concert, but in my book, perhaps the most important one is the creativity. What do I get from watching the concert that I cannot get from making a playlist of their studio-recorded songs and listening to it?
This was something that HASC in the post Mendlowitz days was pretty good at. (and before also, I'm just responding to your post.) There were duets that were not heard anywhere before, there were new songs, and there was a certain mood that allowed viewers to gain a meaningful glimpse into their favorite stars. And the show maintained a decorum that drew viewers, as this was a historic event they were watching, and the show would usually live up to its hype.
I think this is something that has been lacking the last few years. Yes, if I'm in the room, there will be an energy that I'll never be able to get from a CD. But if I'm sitting at home watching on my computer, what do I gain from hearing Beri Weber singing Ribon Kol Haolamim that I would not have from playing the album? What enjoyment do I have from hearing Shwekey sing a bunch of songs that he may have sung better when he was in the studio?
So yes, a great concert the way concerts go, but according to my yardstick of choice, HASC needs to ramp up the creativity and originality of their concerts if they want to appeal to audiences beyond their live one, as they did for 28 or so years.
That's my secondary assessment.
