Among the pre-eminent Chicago harpists from the pre-war period, Costs “Jazz” Gillum was created Sept 11, 1904 in Indianola, Mississippi. He found the harmonica at age six, and five years afterwards ran abroad to live with family members in close by Charleston. After spending his formative years playing road corners and home parties for extra change, Gillum transferred to Chicago in 1923, and in a short time he installed with guitarist Big Costs Broonzy, who frequently played together being a duo in region clubs. Carrying out a few sideman schedules for ARC, he agreed upon with RCA Victor’s Bluebird imprint in 1934 to record being a single artist. His solid relationship with manufacturer Lester Melrose also led to a steady blast of program function, and he was a fixture from the “Bluebird Defeat” house music group. Gillum was drafted in to the Military in 1942, so when he came back from responsibility, his high, reedy harmonica audio had been mainly eclipsed from the harder-edged design of John Lee “Sonny Boy” Williamson. He documented some more edges for Bluebird, but drifted into obscurity from the ’50s, dying after a gunshot wound to the top on March 29, 1966.
