Peter Guralnick

Music writer Peter Guralnick. His new book, "Searching For Robert Johnson," examines the brief life of perhaps the greatest blues musician of all time. In the 20s and 30s, Johnson was "King of the Delta Blues Singers," and a sensation throughout the South. Johnson died at age 27, shot to death by a jealous husband, but his music continued to be studied and copied by artists such as Eric Clapton and the Rolling Stones.

Music critic Peter Guralnick explore the history of soul music by looking at both the impact of individual artists and the role record companies like Motown, Atlantic and Stax played in producing their albums.
