“Terry Callier is an American jazz, soul and folk guitarist, singer and songwriter from Chicago, Illinois. A childhood friend of Curtis Mayfield, Callier began recording in 1963 but never reached stardom despite a series of regional hits in the 1960s and 1970s.
In 1983, he decided to retire from music due to personal reasons. He re-emerged from obscurity when British DJs discovered his old recordings and began to play them in clubs in the early 90s. Acid Jazz Records head Eddie Pillar brought Callier to play clubs in Britain beginning in 1991 and he started to make regular trips over to play during his vacation time from work.” Source
