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.

Lawrence was a fantastic pop singer - for rock, Robert Plant hands down - for blues, Muddy Waters, with Howlin Wolf a close second - for soul, James Brown - for country, Hank Williams - that's quite a wide spectrum, eh?
Rudy Valle,Woody Gutrie,Elvis,John Lennon,Robert Plant(meet twice),Mick Jagger,Micheal Jackson,Hank Williams,Bo Didley,BB King,Willie Nelson

All created styles that changed the face of music for their particular decades.There are a few more that escape me at the moment,one is a blues singer that only made a few recordings.Really bugs me that I cannot remember his name at the moment.Made a recording in Angola Prison.
Joao Gilberto. Miles Davis said: 'he even sounds good when reading the newspaper'
