I don't think she did that bad considering the song. Maybe like a B- The performance as a whole was pretty cool, but she kinda had it easy with the song following the theme of fireworks and explosives.
Like the song, but still don't feel like it'll be as huge as CG&TD.
Katy did an amazing job. Firework is one of the hardest pop songs to perform (Just like Halo, Russian Roulette...) and Katy isn't known for her vocal abilities, yet she did great job on that stage. Better than I expected!
I thought she wasnt going to give a good performance cause Firework is such a hard song to sing...
But, this is actually my favorite live performance she has ever done. I think she sounded really good and better then when she sings songs like Cali Girls and TD
i expected the chorus to be sang horribly since the regular version already shows her voice straining to reach those notes, but she did okay. Not too bad. Unfortunately the verses were pretty bad.
