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.

Oh, by the way... this thread asked for opinions. Connick Jr. was MY opinion, so it surely does belong in this thread. Again, that's just my opinion. Was that repetitive?
Definitely IMO the prophet Edward Kaspel from The Legendary Pink Dots. Has anyone here ever heard him?
How about Brendan Perry of Dead Can Dance?
