They're have a third guitar player on stage since 2008, way before Josh left. I don't know why people make it seem like he was some great guitar god that didn't need a third instrument on stage. The performance is solid, the outro is chilling. Don't really see what there is to hate here, but I guess everyone always has to find something, since they fell from AP's graces. As for the comments on the hair...why? Just leave it alone. It's hair.
I'm not hating. In fact, I still like some Paramore. My comment was purely a technical one. Paramore is a pop-rock band. They play songs that, guitar-wise, at most have a melody going over some chords. One guitarist is needed to play the melodies; one is needed to play the chords. If you need a thicker wall of sound, split the rhythm signal into two separate amp feeds and double the sound through two amplifiers. It's not like the third guitarist stands there and plays something that one of both of the other guitarists isn't playing at any given time. It's just unnecessary. There is literally from a music standpoint no need, no matter how good or bad the music is.
