David Remnick profiles Buddy Guy in The New Yorker:
Three chords. The “one,” the “four,” and the “five.” Twelve bars, more or less. Guy’s devotion and sense of obligation to the blues form began long before the death of B. B. King. The story goes like this.
The son of sharecroppers, George (Buddy) Guy was born in 1936, in the town of Lettsworth, Louisiana, not far from the Mississippi River. On September 25, 1957, he boarded a train and arrived in Chicago, another addition to the Great Migration, the northward exodus of black Southerners that began four decades earlier. But Guy hadn’t come to Chicago to work in the slaughterhouses or the steel mills; he came to play guitar in the blues clubs on the South Side and the West Side. He was twenty-one.
Worth a read—or listen.
