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. Nicknamed "Sleepy" John Estes, supposedly because of his ability to sleep standing up, he teamed with mandolinist Yank Rachell and harmonica player Hammie Nixon to play the house party circuit in and around Brownsville in the early '20s. The same team reunited 40 years later to record for Delmark and play the festival circuit. Never an outstanding guitarist, Estes relied on his expressive voice to carry his music, and the recordings he made from 1929 on have enormous appeal and remain remarkably accessible today.
