I know a dude that got hired to play for her, and he told me the exact same shit about changing up shows she never listened to, and replacing whole bands a day or 2 before the gig. She did that to justify shorting them on the pay. He said he bounced, and then learned the gig got canceled anyway. She's, by far, NOT the only one.
I was playing for Otis Redding, III, and during rehearsals, he'd make a mistake and look in my direction. After the 3rd time, I was like "Nah, pimp. It ain't going down like that!", and I bounced, with the trumpeter running after me asking me to reconsider. I told one of my bass playing friends in The Chi this story, and he said, "Bruh, you dodged a bullet! I know 4 people that played for him, and after the gig, he don't pay. He'll collect the money and leave while the band is waiting for him."
