Robert Pete Williams made his first recordings in the Louisiana State Penitentiary at Angola in 1959 while serving time for murder. Folklorist Dr. Harry Oster was in search of work songs but found instead one of the most original blues artists ever in Williams, who wailed and played guitar with ominous passion and intensity in a visceral style outside the bounds of traditional musical structure, rhyme and meter. Oster’s co-worker Richard Allen noted, ‘He did unorthodox things. He’d be in three modes at once.’ Williams often made up lyrics and improvised accompaniments (picked rather than chorded) as he played, and his subject matter could be stark and disturbing. In one of his best-known songs, ‘Grown So Ugly,’ he looks in the mirror and moans, ‘I got so ugly I don’t even know myself.’ The spontaneous nature of his music made it all but inimitable and it was fitting that one of the few musicians to cover ‘Grown So Ugly’ was an equally unconventional rock icon, Captain Beefheart.

Robert Williams, who added the nickname Pete as a teenager, was born in Zachary, Louisiana, near Baton Rouge, on March 14, 1914. He played music at local gatherings but made his living by farming and working at a dairy, a lumber yard and other odd jobs until he shot a man, in self-defense, he claimed, in a barroom altercation. He entered Angola in 1956 and earned a work parole in 1959 with the support of Oster and others (in a scenario reminiscent of Lead Belly). After songs from his prison sessions appeared on the Louisiana Folklore Society label, the burgeoning folk-blues revival was ready to welcome Williams. His photo appeared in the national press along with news of an invitation to appear at the 1960 Newport Folk Festival. But the parole board refused him permission to travel, and he continued to work on a local farm until his time was served.

His long-anticipated Newport debut in 1964 was recorded by Vanguard, and during the 1960s and ’70s he saw albums released on Folk Lyric, Arhoolie, Bluesville, Takoma and several European labels. He performed widely at folk and blues clubs and various festivals, endearing himself in the process to an international audience who found him anything but murderous. His music made him famous among a select segment of the blues world but not prosperous at home; his jobs during his years of freedom included collecting and selling scrap iron. Williams died on December 31, 1980, in Rosedale, Louisiana.
