Nerves of steel or not, she sang with that in mind and of course sang her damndest. But she actually found the premiere even scarier because she was worried what people outside of this subculture might think just because of the pretense that she's a virtual performer which carries a lot of preconceptions. If she messed up even a little I think she would've taken that very hard.
