Born in Mississippi in 1925, B.B. King is one of the most influential blues singers in America and is a prolific guitarist and song writer.
You've probably heard his work in the form of My Lucille, Sweet Little Angel and Rock Me Baby and nearly anyone who has picked up a guitar can site him as an influence.
B.B King died in his sleep today in Las Vegas due to some diabetes-related illness.
If you're wondering why he was ranked as the third greatest guitarist of all time, take a listen to this performance of 'The Thrill is Gone' live at Montreux in 1993. King was 60 years old.
King has been inducted into the Blues Foundation Hall of Fame and the Rock and Roll Hall of Fame, and toured non-stop up until very recently, often performing more than 100 concerts a year.
B.B. King is nothing less of a legend, and he will be sorely missed.
