Kill City is one of my favorite albums of all time.  I would say that it is in my list 75 albums all time.   The original vinyl record was green.

Iggy recorded this album in 1975 while on weekend pass from a mental hospital he was going to quit his drug addiction.

 I see Iggy’s kill city as a bridge catharsis from his unsustainable drug(heroin) induced lifestyle to his next stages of art/life and creativity.
