I'll give you three of examples. I recall hearing Eva Cassidy singing 'Over The Rainbow', and I was stunned by the power and beauty of her extraordinary voice. She was singing 'Over The Rainbow, and she put me over the moon. I went straight out and bought her cd.

My second example goes back to the 50s, and it's the first time I heard the original lead singer of the Platters singing, 'Smoke Gets In Your Eyes'. I don't know this gentleman's name, but his amazing vocals blew me away.

Finally, back in the 60s, I heard John Fogerty sing 'Heard It Through The Grapevine'. When I think of great rock 'n roll voices, I think of Mr. Fogerty.
