I'm sorry if I'm bringing idpol shit into this, but I dont care that rob halford is gay. Guy is an absolute beast of a vocalist (even now at his old age). Just listen to the songs 'all guns blazing' and 'hell patrol' off of their 1990 album painkiller (and he still sings the song painkiller live in concerts to this day, even at his current age! One of the greatest clean vocalists in metal (I know hes a common pick for one of the best metal singers, but it's for good reason). One of my favorite vocalists aside from Robert plant, frank mullen from suffocation, phil anselmo, killjoy from necrophagia, bill steer / jeff walker from carcass, and dax riggs from acid bath.
