Hassan El-Tayyab was a special-ed teacher going through a rough patch in 2009 when he decided to hop in his Chevy Malibu and take a road trip through America. He settled in Berkeley and formed a new Americana music group with singer-songwriter Shiloh Parkerson. The band, American Nomad, describes itself as “modern-day troubadours tramping the dark and dangerous highways of the human soul,” from heartbreak to broken dreams, with a traditional folk sound. The group just released its new CD, “Country Mile.” They join us for a conversation and live performance.
