Astat covered the guitar and mix aspects of this song well but let me clarify a few things on Chester's vocals. As Mark said earlier, we are used to hearing Chester's vocals be pitch corrected. (Not sure what you meant by "layers" Mark, AutoTune and Melodyne simply shift pitches up or down to be perfectly on the correct note). Now I don't believe they do as much to his vocals as a lot of singers out there but there is something else that is clearly not on the vocal track and that is reverb/delay. Ever wonder why you sound way better when you sing in the shower? It's because the early reflections coming off the tile in a small enclosed space cover up the little inconsistencies in your voice. That's basically reverb. Most vocals have at least a little bit of reverb and often a bit of slap delay as well to create a fuller spacier sound. I hear neither on this song. And I prefer it that way if the goal was to have a raw, natural sounding mix. I expect Chester to be able to NAIL this song live because he doesn't have to try to match an overproduced pitch corrected album track. I'm interested to hear the mix on the rest of this album.
