Terry Callier (born 24 May 1945) is an American jazz, soul and folk guitarist and singer-songwriter from Chicago, Illinois. Callier, a childhood friend of Curtis Mayfield, began recording in 1963 but never reached stardom despite a series of regional hits in the 1960s and 70s and three outstanding albums for Cadet: Occasional Rain (1972), What Colour Is Love? (1973) and I Just Can’t Help Myself (1975). In 1983, he gained custody of his 12-year-old daughter Sundiata and decided to retire from music to look for a steadier income. He took classes in computer programming and landed a job at the University of Chicago in 1984.
