I've played on Wicked and played piano behind Kristen on plenty of her personal gigs. Trust me, not only her but most of these "celebrity" types - especially Broadway ones - are unbelievably cringey with everything. They really believe their own shit. I've played behind her literally biting my lip until it almost bled to keep myself from rolling my eyes to the back of my head. It's not like when the lights go down and we're backstage that all of a sudden she's all cool and smoking a joint and talking normal. That shit you see singing, she tries to keep that shit cringey personality going 24/7 and she's not the only one.
I'm not gonna lie - considering I've been out of work more or less for almost a year since the lockdown started, performing with twats like Kristin and her ilk I DO NOT miss in the slightest. It's actually been a really nice vacation from these vapid twats.
