Arthur 'Big Boy' Crudup was an influential delta and Chicago bluesman; and was highly active in the 40's and early 50's.
His smooth soft voice and superb guitar playing made him one of the main pillars of the blues; even Elvis covered his songs, particularly 'So Glad You're Mine'.
He started out performing in the blues Mecca, Clarksdale, Mississippi before moving to Chicago in the late 1930's where he recorded and performed. His career fluctuated up and down, due to royalty disputes, and went back to Mississippi, where he returned to normal work. He did record in the mid 60's however, and died in 1974.
