<p>I have a German book called The Greatest Singers of the 20th Century. Randomly  opening the book, I picked four singers to profile. I did not pick the real famous like Caruso, nor did I pick myself (I was not in the book), but four singers you are really going to enjoy.</p>

The Angry Tenor rants

Former heldentenor John Sayers discusses his time on the opera stage and other interests of the arts world. From opera to jazz and ballet to abstract art, John has an opinion and he is not afraid to share it.     During his career, he sang with many well-known singers, stage directors and conductors.      After retiring from singing, he wrote and edited the EastSider, an arts and entertainment newspaper in south Florida.      He also created The Opera Minute for NPR on the Treasure Coast.      He has published one book and is working hard on his second, which shall be full of wonder and surprises.
