I was forced upstairs to listen to Music, since Mark was doing drum-practice...
So, I listened to the "Escape Live" CD - the one that was with the "Collector's Edition" DVD - on our "Surround Sound" Radio/CD player in our room...
And it occurred to me:
The Escape Tour happened in 1981: my Freshman Year in High School....I remember a lot of kids thinking "oh, he has such a high voice; that's all he has..." I remember my sister's friends, who were 2 or 3 years older than me, thinking the same thing.
So, flash-forward to 1983: Frontiers:
These same people are saying, "What HAPPENED to him? His voice is so low!!"
By the time ROR came along....keep in mind, this is WITH "Street Talk".....most of my peers thought "oh, his voice is GOING..."
From my point of view - at Front-&-Center Lead Vocalist - all I can say is:
Most Lead Vocalists can "stake their claim" with one sound:
Steve Perry managed to do that - with TWO DISTINCTIVE VOCAL RANGES: Infinity-Escape

Give him Credit where Credit is due....and stop with the THINKING that he lost his Voice.
He didn't "lose" it....he just changed it.
