Screech? He does way more than that. His range, vibrato and ability to hold a note is incredible. Not only that, he sounds as good live as he does on the album. Not many vocalists sound real good live. He can hold a note without vibrato that doesn't even waver off tone.
I liked them like other bands of their time when it was big. My wife re-introduced me to Skid Row a few years ago and that is when I really noticed the vocal talent. Some of the lesser known tunes really show his voice off better.
