John Adam Estes (January 25, 1899 or 1904 — June 5, 1977), best known as Sleepy John Estes or Sleepy John, was a U.S. blues guitarist, songwriter and vocalist, born in Ripley, Lauderdale County, Tennessee.
Estes made his debut as a recording artist in Memphis, Tennessee in 1929, at a session organized by Ralph Peer for Victor Records. His partnership with Nixon was first documented on songs such as "Drop Down Mama" and "Someday Baby Blues" in 1935; later sides replaced the harmonica player with the guitarists Son Bonds or Charlie Pickett. He later recorded for the Decca and Bluebird labels, with his last pre-war recording session taking place in 1941. He made a brief return to recording at Sun Studio in Memphis in 1952, recording "Runnin' Around" and "Rats in My Kitchen", but otherwise was largely out of the public eye for two decades.
Estes was a fine singer, with a distinctive "crying" vocal style. He frequently teamed with more capable musicians, like "Yank" Rachell, Hammie Nixon, and the piano player Jab Jones. Estes sounded so much like an old man, even on his early records, that blues revivalists reportedly delayed looking for him because they assumed he would have to be long dead, and because fellow musician Big Bill Broonzy had written that Estes had died. By the time he was tracked down, by Bob Koester and Samuel Charters in 1962, he had become completely blind and was living in poverty. He resumed touring and recording, reunited with Nixon and toured Europe several times and Japan, with a clutch of albums released on the Delmark Records label. Though his later records are generally considered less interesting than his pre-war output. Nevertheless, Estes, Nixon and Rachell also made a successful appearance at the 1964 Newport Folk Festival.
Bob Dylan mentions Estes in the sleevenotes to Bringing It All Back Home (1965).
