The video from that program will be available online for a few more days. The Tonight Show keeps each full show up for web viewing for a week after it airs, so until Saturday, you can catch this one online. I was able to catch the performance live on Friday night, and enjoyed it very much.
Just go to the Tonight Show video page, select the 2/29 program and when it loads, you can click to the final marker in the time line to watch their performance of Punch Bowl. If polyphonic dissonance is hard on your ears, this one might pose a challenge, but give it a chance.
It’s adventurous music, and it struck me as fascinating to watch them pull it off live.
