Is it a musical or straight play? I know nothing about it.
It's... neither? Four comedians are onstage to read short stories written by Simon Rich about ego, envy, greed (the tag line includes "and basically just New Yorkers in general"). The band is part of some of the stories, and links the stories together in between readings. The stories were funny, poignant, interesting. I was very pleased to see Brady and Gaffigan- although I think Gaffigan is funnier when he is doing his own stuff. Brady was exceptional, and he sang with the band for part of one number. We got the tickets thru TKTS for $50, so I think it was worth the price, but it was different. If you are looking for either a musical or a full play? I don't think it'd fit your bill... but I enjoyed it.
On the second night, I bit the bullet, paid stubhub prices, and went to NYCB's Nutcracker to see Tiler Peck dance as the Sugar Plum fairy. I have seen a LOT of ballet, both live and on film, and my daughter trained as a ballerina so I know somewhat of what I am talking about here, but I have NEVER in my life seen a dancer as strong or amazing as Tiler Peck. She was phenomenal. It was worth every penny, and more, to see her dance.
[To put this in context, I should add that this was a "bucket list" thing for DD and me. We have talked for decades of making a holiday trip to NYC in Decembr to see the Rockettes Christmas Show (DD trained with them but was too short to make the line at auditions) and NYCB's Nutcracker (DD's ballet teacher danced for Balanchine at NYCB) but DD was always performing in Nut with a traveling company so her weekends were spoken for, so the trip never happened. However, this year the studio where she teaches and dances was doing a trip to see the Rockettes and take a class, so we decided to go to. Seeing Nut was a last minute decision, but one of the best I have ever made!]
