John Adam Estes (January 25, 1899 or 1904 – June 5, 1977)
Big Bill Broonzy called John Estes' style of singing "crying" the blues because of its overt emotional quality. Actually, his vocal style harks back to his tenure as a work-gang leader for a railroad maintenance crew, where his vocal improvisations and keen, cutting voice set the pace for work activities
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.
Some accounts attribute his nickname "Sleepy" to a blood pressure disorder and/or narcolepsy. Others, such as blues historian Bob Koester, claim he simply had a "tendency to withdraw from his surroundings into drowsiness whenever life was too cruel or too boring to warrant full attention"
Many of Estes' original songs were based on events in his own life or on people he knew from his home town of Brownsville, Tennessee, such as the local lawyer ("Lawyer Clark Blues"), local auto mechanic ("Vassie Williams' Blues"), or an amorously inclined teenage girl ("Little Laura Blues")
He also dispensed advice on agricultural matters ("Working Man Blues") and chronicled his own attempt to reach a recording studio for a session by hopping a freight train ("Special Agent (Railroad Police Blues)"). His lyrics combined keen observation with an ability to turn an effective phrase.
Estes suffered a stroke while preparing for a European tour, and died on June 5, 1977, at his home of 17 years in Brownsville, Tennessee
