Definitely Robert Plant because he did so many genres well, but I was really surprised the first time I heard Axl Rose. I really couldn't believe he was vocals on Mr. Brownstone AND the rest of the album. I would have sworn it was two different people. I also always loved STP and Alice in Chains and Soundgarden. So gritty.
Not a bad voice on the list. Two missing for me are Eddie Vedder, bags of soul in his voice and Maynard Keenan. Once described as 'the human vioce'.
I have to add Brad Delp, late lead of Boston. Such power, range, and lung capacity. Anyone who's ever played Rock band or Singstar has to respect this guy.
Well, since it's favorite rock vocalists (not best) I'll throw my hat in the ring with Bob Pollard, front man for the greatest live band in the history of rock n' roll, Guided by Voices. People in my generation moan about missing out on Jim Morrison and Bon Scott, my children will moan about missing out on Mr. Pollard. Truly entertainment incarnate!
Ian Gillan - Deep Purple, "Child in Time" blows me away.
It is totally the nerd in me but when I hear Robert Plant all I hear is "mmmmmmmmmmmmmmmmmmm SSL input compressors....."
Sorry if no one gets that...
Quite obviously, it's Freddie Mercury!
My top 3
1. Chris Cornell (Soundgarden/Audioslave)
2. Rob Halford (Judas Priest)
3. David Lee Roth (Van Halen) there's no one else in the world like Diamond Dave!
Honorable Mention: Sebastian Bach
On a side note... Sebastian Bach is obviously a better vocalist than DLR but I'm a Van Halen fanboy.
