Ronnie James Fio is obviously one of the best vocalist I've ever heard. There are also Timo
Kotipelto from
Stratovarius, Tobias Sammet from
Edguy and Tony Kakko from
Sonata Arctica who is clearly a great vocalist(he is at the top of his game in Sonata's last album).
Bruce Dickinson is not the best technically but he has a very powerful
Voice and his live performance are simply amazing!
