Not a terrible performance but there were some tracked backing vocals in the second and third chorus. Plus his screaming here was terrible. Idk if he was sick or what but damn it was bad
He was exhausted from touring and performing so much so yeah his voice isn't going to be 100% there, also take into consideration that they party and drink alcohol before and after shows, stay up late and have to play the next, so yeah that will affect the voice. Also he's not singing but more yelling, not properly but still it's the style of this music. Love adtr though!
