Definitely Chester's voice. My question, which I know nobody here can answer, is why Garrix decided to scratch Chester's vocals and not include them in the official release.
Mike sings really well on this song, and I'm taking nothing from his performance, but this is Chester Bennington. Why take his voice off the song?
If he was going to do that, then what was with him saying "because of Chester's passing it's little bit hard to release the song. I don't know if we're ever gonna release it."?
Did he scratch Chester's vocals BECAUSE he passed? If so, that makes no sense unless Chester personally didn't like his vocals on the song or something.
