WBLU is proud to feature Magnuson Blues, a weekly Blues show with John Wooler. Every Wednesday at noon and Friday at 7 pm eastern. The blues has deep roots in American history, particularly African-American history. The blues originated on Southern plantations in the 19th Century. Its inventors were slaves, ex-slaves and the descendants of slaves—African-American sharecroppers who sang as they toiled in the cotton and vegetable fields. It's generally accepted that the music evolved from African spirituals, African chants, work songs, field hollers, rural fife and drum music, revivalist hymns, and country dance music.
