Early blues pianist Bob Call is known for recording with vocalist Elzadie Robinson in Chicago during the 1920s, even though he recorded as an accompanist after WWII. Call is believed to come from Texas, but by the late '20s he was residing in Chicago and befriended pianist Will Ezell. Both alternately accompanied singer Elzadie Robinson during her Paramount recordings. Bob Call also recorded the song "31 Blues" solo for the Brunswick label in late 1929, and accompanied blues vocalist James "Boodle It" Wiggins during that time. Among Call's late '20s recordings are these; several for Vocalion that went unissued, and his own featured dates for Paramount, which included his take on "Keep A-Knockin' An You Can't Get In." The 1930s found Call studying music in Chicago. He went back to recording as accompanist after WWII, and still resided in Chicago as of the late '60s.
