Legendary Arhoolie Records founder Chris Strachwitz transversed the United States and Mexico for decades recording traditional roots music and unknown artists. The El Cerrito-based producer, who died last year, was known for his ear for music, but he also had an eye for capturing images. More than 150 of those photos documenting his travels and recording sessions are collected in a new book, “Arhoolie Records Down Home Music: The Stories and Photographs of Chris Strachwitz.” Co-author and veteran music journalist Joel Selvin joins us to talk about Strachwitz’s art and legacy. Guest: Joel Selvin, San Francisco-based music journalist and author. His latest book is "Arhoolie Records: Down Home Music."
