I've noticed in performances of Waiting For The End, Brad is standing at the keyboard and Mike has a guitar, but Mike isn't playing for the intro, so who's playing the guitar intro?
The intro isn't guitar, it's a synth sequence. There's no guitar in WFTE until Chester's first chorus part starts. Nope, the only thing Brad plays on keys is the single repeating piano note that plays throughout most of the song. I think the uber-distorted low E notes are done by Joe.
