"Sweet Black Angel" (sometimes known as "Black Angel") is a song by The Rolling Stones, featured on their 1972 album Exile on Main St. It was also released on a single as the B-side to "Tumbling Dice" prior to the album.

Written by Mick Jagger and Keith Richards, "Sweet Black Angel" is one of the few outright political songs written by the Rolling Stones. A country-blues ballad, the song was written about civil rights activist Angela Davis, who was facing murder charges at the time. Steve Kurutz says in his review, "Having never heard of Angela Davis, a listener could easily overlook the political lyrics and get lost in the circular acoustic plucking or the washboard rhythm that propels the song so well. Yet, by knowing the case history one realizes how deft and clever Mick's lyrics could be, even if he hides behind his best backwoods diction and garbled annunciation [sic] obscure[s] the point."

Initial recording took place at Mick Jagger's home in England "Stargroves' in mid 1970 during the Sticky Fingers sessions and overdubs and final mixing were later done at Sunset Sound Studios in Los Angeles between the months of December, 1971, and March, 1972. Jagger is on lead vocals, Richards and Mick Taylor guitars, Bill Wyman bass, and Charlie Watts drums. Richard "Didymus" Washington plays marimba while producer Jimmy Miller lends support percussion.

Black Angel is a 1946 film noir, based on the novel The Black Angel by Cornell Woolrich. The film was director Roy William Neill's last film.

A falsely convicted man's wife, Catherine (June Vincent), and an alcoholic composer and pianist, Martin (Dan Duryea), team up in an attempt to clear her husband of the murder of a blonde singer, who is Martin's wife. Their investigation leads them to face-to-face confrontations with a determined policeman (Broderick Crawford) and a shifty nightclub owner (Peter Lorre), who Catherine and Martin suspect may be the real killer.

Dark City: The Film Noir, by Spencer Selby, calls Black Angel: "Important, stylish B-noir, featuring Dan Duryea as the ironic central character."

Writer Cornell Woolrich hated this adaption of his story which, aside from the conclusion, differed greatly from his book.

Black Angel is referenced in the 2006 noir-influenced film The Black Dahlia starring Scarlett Johansson and Hilary Swank. It is the movie shown playing at the cinema featured in the rainy street scene.

Earl Hooker (January 15, 1929 – April 21, 1970) was an American Chicago blues guitarist, perhaps best known for his slide guitar playing. Considered a "musician's musician", Hooker performed with blues artists such as Sonny Boy Williamson II, Junior Wells, and John Lee Hooker (a cousin) as well as fronting his own bands. An early player of the electric guitar, Hooker was influenced by the modern urban styles of T-Bone Walker and Robert Nighthawk. As a band leader, he recorded several singles and albums, in addition to recording with well-known artists. His "Blue Guitar", a popular Chicago area slide-guitar instrumental single, was later overdubbed with vocals by Muddy Waters and became the popular "You Shook Me".

In the late 1960s, Hooker began performing on the college and concert circuit and had several recording contracts. Just as his career was on an upswing, Earl Hooker died in 1970 at age 41 after a lifelong struggle with tuberculosis. His guitar playing has been acknowledged by many of his peers, including B.B. King, who commented: "to me he is the best of modern guitarists. Period. With the slide he was the best. It was nobody else like him, he was just one of a kind".

Robert Lee McCollum (November 30, 1909 – November 5, 1967) was an American blues musician, who played and recorded under the pseudonyms Robert Lee McCoy and Robert Nighthawk.

Born in Helena, Arkansas, he left home at an early age to become a busking musician, and after a period wandering through southern Mississippi, settled for a time in Memphis, Tennessee where he played with local orchestras and musicians, such as the Memphis Jug Band. A particular influence during this period was Houston Stackhouse, from whom he learnt to play slide guitar, and with whom he appeared on the radio in Jackson, Mississippi.

After further travels through Mississippi, he found it advisable to take his mother's name, and as Robert Lee McCoy moved to St. Louis, Missouri in the mid 1930s. Local musicians with whom he played included Henry Townsend, Big Joe Williams, and Sonny Boy Williamson. This led to two recording dates in 1937, the four musicians recording together at the Victor Records studio in Aurora, Illinois as well as recordings under his own name, including "Prowling Night-Hawk" (recorded 5 May 1937), from which he was take his later pseudonym.

George "Buddy" Guy (born July 30, 1936) is an American blues guitarist and singer. Critically acclaimed, he is a pioneer of the Chicago blues sound and has served as an influence to some of the most notable musicians of his generation. "A key influence on Eric Clapton, Jimi Hendrix and Stevie Ray Vaughan, Buddy Guy put the Louisiana hurricane in 1960s electric Chicago blues as a member of Muddy Waters' band and as a house guitarist at Chess Records. A native of the Baton Rouge area, he combined a blazing modernism with a fierce grip on his roots, playing frantic leads heavy with swampy funk on Howlin' Wolf's 'Killing Floor' and Koko Taylor's 'Wang Dang Doodle' as well as on his own Chess sides and the fine series of records he made with harp man Junior Wells. One of the last active connections to the golden age of Chess, Guy still plays with his original fire."

Ranked thirtieth in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time", Guy is known for his showmanship on stage: playing his guitar with drumsticks or strolling into the audience while playing solos. His song "Stone Crazy" was ranked seventy-eighth in list of the 100 Greatest Guitar Songs of All Time also of Rolling Stone.
