That big bass note in Weekapaug came from the marimba! I was thankfully close enough to see Trey hammer down on the low ends to create a wonderfully body rumble.

...and at least from my perspective, the crowd pretty much sang the entirety of Character Zero (with the band filling in on the chorus). Trey had a huge shit eating grin at the time, and kept looking over at Page in disbelief that the crowd was rocking it that hard. He even turned his mike stand around at some point, pretty content to let the crowd take over the vocals.

Other personal highlight for me from the show is having Page point and laugh at my "ass handed" sign as they walked off at set break. And I definitely got my ass handed to me that show!
