Last month, one of the great explorers and producers of American vernacular music, Chris Strachwitz, passed away. He was 91 years old. He was the founder and co-owner (with Tom Diamant) of Arhoolie Records which since its first release in 1960, Texas Sharecropper And Songster by Texan bluesman Mance Lipscomb, has put out an astonishing 44,000 records.
