One hundred years ago, a boy-child was born in Mississippi – a dirt-poor, African-American who would grow up, learn to sing and play the blues, and eventually achieve worldwide renown. In the decades after his death, he has become known as the King of the Delta Blues Singers, his music expanding in influence to the point that rock stars of the greatest magnitude – the Rolling Stones, Bob Dylan, Eric Clapton, the Allman Brothers – all sing his praise and have recorded his songs.

That boy-child was Robert Johnson, an itinerant blues singer and guitarist who lived from 1911 to 1938. He recorded 29 songs between 1936 and ‘37 for the American Record Corporation, which released eleven 78rpm records on their Vocalion label during Johnson¹s lifetime, and one after his death.

Most of these tunes have attained canonical status, and are now considered enduring anthems of the genre: “Cross Road Blues,” “Love In Vain,” “Hellhound On My Trail,” “I Believe I¹ll Dust My Broom,” “Walking Blues,” “Sweet Home Chicago.”

Like many bluesmen of his day, Johnson plied his craft on street corners and in jook joints, ever rambling and ever lonely – and writing songs that romanticized that existence. But Johnson accomplished this with such an unprecedented intensity, marrying his starkly expressive vocals with a guitar mastery, that his music has endured long after the heyday of country blues and his own short life.

Never had the hardships of the world been transformed into such a poetic height; never had the blues plumbed such an emotional depth. Johnson took the intense loneliness, terrors and tortuous lifestyle that came with being an African-American in the South during the Great Depression, and transformed that specific and very personal experience into music of universal relevance and global reach. “You want to know how good the blues can get?” Keith Richards once asked, answering his own question: “Well, this is it.” Eric Clapton put it more plainly: “I have never found anything more deeply soulful than Robert Johnson.”

The power of Johnson’s music has been amplified over the years by the fact that so little about him is known and what little biographical information we now have only revealed itself at an almost glacial pace. Myths surrounding his life took over: that he was a country boy turned ladies’ man; that he only achieved his uncanny musical mastery after selling his soul to the devil. Even the tragedy of his death seemed to grow to mythic proportion: being poisoned by a jealous boyfriend then taking three days to expire, even as the legendary talent scout John Hammond was searching him out to perform at Carnegie Hall in New York City.

In 1990, Sony Legacy produced and released the 2-CD box set Robert Johnson: The Complete Recordings to widespread critical acclaim and, for a country blues reissue, unprecedented sales. The Complete Recordings proved the existence of a potential market for music from the deepest reaches of Sony¹s catalog, especially if buoyed by a strong story with mainstream appeal. Johnson¹s legend continues to attract an ever-widening audience, with no sign of abating. If, in today¹s world of hip-hop and heavy metal, a person knows of only one country blues artist, odds are it is Robert Johnson.
