Although he played an 88 string guitar, I think that Ray Charles was the most expressive blues singer and instrumentalist there ever was.
Like so many of the other bluesmen, his style was formed in Gospel. In a very real sense, he was a true folk singer.
Staying on topic, I was remembering the days when Philadelphia Jerry Ricks was, just, Jerry Ricks. He used to joke about changing his name
to Blind Sweet Willie Tishman. Hey, it was a long time ago.
