With his amazing songwriting and voice and the ability to put it all out there he's the best to ever do it !!! Extremely underrated I'm all the way in Idaho! Iv got to see him twice and it's something il never forget !
Its certainly a bit more grainy but that can come with age and use/abuse. His pitch is still really clean and hes intentionally adding a sort of scream technique in there which comes across okay. Its a relatively high note to hit for a normal male voice, but overall I would say that his voice is normal for his age and career.
