'I Been Down So Long' - Louisiana Red

Iverson Minter, known as Louisiana Red, was a prolific bluesman. He began recording for Chess Records in 1949, but then joined the Army. After his discharge, he played with John Lee Hooker in Detroit in the late '50s, and he recorded and performed heavily in the 1960s and 1970's. He moved Germany 1981 and stayed there until his death in 2012. 

In 1983 he won a W.C. Handy Award for Best Traditional Blues Male Artist. 

His style is mostly acoustic Delta blues, but the song below shows off his Chicago style.
