Most people don’t realize that the Elvis hit “Hound Dog” was actually a cover and first a hit by Big Mama Thornton. The first video gets even better when it shifts to Down Home Shakedown with all the harmonica work (note: John Lee Hooker is on the video too).
Thornton is definitely an underrated blues singer.
