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.

Yeah sure. Janis can't sing the blues. Just ask Jim Morrison. OOPS, too late.
I am starting to feel Eddie Vedder is our best rock singer. Lightning Bolt tour is a defining moment on how well his voice has matured.
A tie for me, both jazz guys: Mark Murphy and Johnny Hartman. Such different styles, so both are the best to me.
