Around 1910 Sam Chatmon formed a family string band with seven of his siblings that would later develop into the Mississippi Sheiks.
In 1936 Sam and his brother Lonnie made twelve recordings as the Chatman [sic] Brothers; Sam did not record again for twenty-four years. During that time he worked as a farmer, a night watchman, and a plantation supervisor.
In 1960 Chris Strachwitz rediscovered Chatmon and recorded him; four of the songs recorded were included on the Arhoolie LP I have to paint my face. In 1966 he was rediscovered again by the blues enthusiast Ken Swerilas, who persuaded him to move to San Diego, where he began playing in clubs and became a local favorite. Soon he was performing around the country at folk festivals and clubs, gaining notoriety as one of the few surviving first-generation Mississippi bluesmen. He made his last professional appearance at the 1982 Mississippi Delta Blues Festival.
This according to “Chatmon, Sam” by Andrew Leach (Encyclopedia of the blues II  p. 195); this encyclopedia is one of many resources included in RILM music encyclopedias, an ever-expanding full-text compilation of reference works.
Today is Chatmon’s 120th birthday! A discography is here. Below, ca. 1978.
George “Buddy” Guy started working as a sideman for Chess Records in 1959 and quickly became a much sought-after guitarist, working with the likes of Muddy Waters, Little Walter, and Howlin’ Wolf. During the 1970s he toured and recorded with Junior Wells, and although the duo was revered in blues circles—they even opened for The Rolling Stones on several occasions—their records were often badly distributed and sold poorly.
But during the 1980s Guy’s reputation grew steadily, and in 1985 he was inducted into the Blues Hall of Fame. By the 1990s he had become an electric guitar icon, having been cited as a major influence by legendary rock guitarists including Jimi Hendrix, Stevie Ray Vaughan, and Eric Clapton.
This according to “Guy, George ‘Buddy’” by Yves Laberge (Encyclopedia of the blues II  pp. 395–396); this encyclopedia is one of many resources included in RILM music encyclopedias, an ever-expanding full-text compilation of reference works.

One day Manny Greenhill, Reverend Gary Davis’s sometime manager, received a desperate call from Wurlitzer, one of Boston’s most staid and respected music stores.
A quavering voice explained that an elderly man, a minister of some sort, had seized the most expensive guitar in the store and refused to part with it.
The man had tried out several models, had chosen the top-of-the-line Gibson, and had been there for some time, talking to it, and playing and singing spirituals in a loud voice. No one dared to take it away from him. “He says he has no money, but he gave your name, Mr. Greenhill, as his manager. He is upsetting the other customers. What shall we do?”
Greenhill bought Davis the guitar, and the debt became a longstanding joke: Davis was always going to pay him back for Miss Gibson “on the next check.”
This according to “Remembering Reverend Gary Davis” by Eric von Schmidt and John Kruth (Sing out! LI/4 [winter 2008] pp. 66–75).
Today is Davis’s 120th birthday! Below, Davis and Miss Gibson in action.
Gertrude “Ma” Rainey’s Prove it on me blues affirms her independence from orthodox norms by boldly celebrating her lesbianism.
Rainey’s sexual involvement with women was no secret with both colleagues and audiences. The advertisement for the song (above, click to enlarge) shows her dressed as a man, obviously flirting with two women, while a policeman keeps an eye on her.
The song’s lyrics include:
They said I do it, ain’t nobody caught me/Sure got to prove it on me
Went out last night with a crowd of my friends/They must’ve been women, ‘cause I don’t like no men
It’s true I wear a collar and tie/Make the wind blow all the while
‘Cause they say I do it, ain’t nobody caught me/They sure got to prove it on me
This according to Blues legacies and black feminism: “Ma” Rainey, Bessie Smith, and Billie Holiday by Angela Y. Davis (New York: Pantheon, 1998 p. 39)
Today is Rainey’s 130th birthday! Below, the 1928 recording.
The music of Roosevelt Sykes demolishes the notion that blues is too depressing to enjoy.
His romping boogies and risqué lyrics such as Dirty mother, Ice cream freezer, and Peeping Tom characterize his monumental contributions to the blues idiom; he was also responsible for the influential pieces 44 blues, Driving wheel, and Night time is the right time, and his rollicking version of Sweet home Chicago presaged all the covers that would surface later on.
This according to “Roosevelt Sykes could play those 88s” (The African American Registry, 2006).
Today would have been Sykes’s 110 birthday! Below, his signature song The honeydripper.
In an interview, Bobo Jenkins discussed the genesis of his first song and hit recording, Democrat blues.
He wrote the song on election day in 1952, while Eisenhower was being elected. He explained that it was really a song about the Great Depression and the especially hard economic times that plagued the poor during Republican administrations.
“I was workin’ out to Chrysler…and I sat down at the end of the line and wrote that song…The whirrin’ of the machines gives me the beat. It’s like listening to a band play all day. Every song I ever wrote that’s any good came to me on the assembly line.”
In 1954, with the help from John Lee Hooker, he went to Chess Records with his new song. “So I goes to Chicago with my guitar and a little amplifier, and the man says ‘What you got now? Usually everybody comes from Mississippi and brings a hit with them.’ I said, well, ‘I’m from Mississippi.’ See, I was lyin’ ‘cause I was livin’ in Detroit, but it sound good to hear it.”
This according to Bobo Jenkins: A bluesman’s journey by Fred Reif (Detroit: Detroit Music History, 2001).
Today would have been Jenkins’s 100th birthday! Below, the original Chess recording.
B.B. King’s guitar technique drew from many sources, both direct and indirect.
At first he functioned primarily as a vocalist, making little idiomatic use of the instrument; in subsequent recordings the influence of T-Bone Walker became quite apparent.
He also adapted embellishments used by earlier blues guitarists (Lonnie Johnson) as well as those of jazz guitarists (Charlie Christian, Django Reinhardt, Bill Jennings). King’s distinctive finger tremolo was inspired by Bukka White’s bottleneck style.
This according to “B.B. King: Analysis of the artist’s evolving guitar technique” by Jerry Richardson (American Music Research Center journal VI  pp. 89–107.
Today would have been King’s 90th birthday! Below, live in 1974.
Using conventional musical devices for blues compositions as a basis, Willie Dixon expanded the possibilities for blues songwriting by introducing elements from pop song forms, using a quatrain refrain text form with longer musical structures than a 12-bar form, and amalgamating the 12-bar/a-a-b form with the 16-bar/quatrain refrain form in different sections of a composition.
Dixon also helped artists such as Muddy Waters, Howlin’ Wolf, and Koko Taylor to intensify their public images; his development of their performing personae is relevant to the tradition of the blues as a secular religion, and Dixon’s casting of them originated in traditional black badman tales circulated in the postbellum South.
This according to Willie Dixon’s work on the blues: From the early recordings through the Chess and Cobra years, 1940–1971 by Mitsutoshi Inaba, a dissertation accepted by the University of Oregon in 2005.
Today is Dixon’s 100th birthday! Below, he sings his own Back door man, first recorded by Howlin’ Wolf in 1960; the song is a classic example of Dixon’s innovations in blues song forms.

Junior Wells began working as a street musician when he was 7 years old, and when he was 18 he replaced Little Walter as Muddy Waters’s harmonica player.
In 1958 he started performing with the guitarist Buddy Guy, and their band became a fixture on the blues circuit until they went separate ways in 1978.
Some of Wells’s best recorded work came during this time, on tight, exciting records made for Delmark, like the 1965 Hoodoo man blues. The band became a favorite of rock musicians, and during that period Wells and Guy played to rock audiences at the Fillmore West and made a State Department tour of East Africa; in 1970 they toured with Canned Heat and The Rolling Stones.
This according to “Junior Wells, central player in Chicago blues, is dead at 63” by Ben Ratliff (The New York times CXLVII/51,040 [17 January 1998] p. A11).
Today would have been Wells’s 80th birthday! Below, Wells and Guy at the Montreaux Jazz Festival in the band’s heyday.
The roadhouse is an American institution—the little bar on the edge of town that comes alive when the sun comes down with back-to-basics roots music. Texas is the honorary home of roadhouse music, and Stevie Ray Vaughan was its uncrowned king.
Vaughan arrived in a blaze of guitar glory in the early 1980s, following on the trail of his Texas forebears from electric guitar pioneers like Eddie Durham and Charlie Christian to blues legends like T-Bone Walker, Freddie King, Albert Collins, and his own big brother Jimmie.
This according to Roadhouse blues: Stevie Ray Vaughan and Texas R&B by Hugh Gregory (San Francisco: Backbeat Books, 2003).
Today would have been Vaughan’s 60th birthday! Below, live in 1982.
