Best Male Singers of the 20th Century


There is an interesting current discussion about the best female vocalists on CD. I have my own ideas about the best male singers (any category) of the 20th Century, but would like to hear other opinions.

I agree with Lbietz2001 about Josh Groban. His voice is nearly unbelieveable, especially for someone so young (20, maybe 21 now)...but he's a figure from the 21st Century. My nominees from the 20th Century would include Jose Cura and Carlo Bergonzi for opera; Dean Martin, Harry Connick, Perry Como for pop: Lionel Ritchie and Smokey Robinson for soft rock.
Smoky Robinson: "Tracks Of My Tears", and " My Girl Has Gone". Marvin gay.
Eric Clapton: "Sunshine of Your Love", and Others.
Alot of older artists: Roy Orbison, etc.
Newer ones to me are the singers from Aerosmith, and Metallica.
Don Van Vliet,Damo Suzuki,Lee Ving,
Kurt Cobain,Suzanne Lewis,Howlin" Wolf,and of course the venerable Yoshida Tatsuya and Sasaki Hisashi
