Okay cool, I get that, Bobby has really high and harsh vocals, not for everyone.
I find them to be pretty epic considering they've got 19 studio albums. Dang impressive, they're still active and also have two of their founding members remaining. And, at least in my opinion, all of the albums are good, not a single bad one there, somehow they've managed to write albums that are distinct from each other over the course of 30 years without losing their signature sound.
