Just want to warn you

Curtis Mayfield, Short Eyes (Curtom 1977)
On his soundtrack to the 1977 film Short Eyes, Mayfield turns from the streets to the prisons, finding empathy for both the victims and the dehumanized inmates. Like many of his albums the beauty of the music gives an edge of hope to the bleak lyrics. LP comes with the rather creepy illustrated lyric sheet seen below.
