What's a country music legend to do when country radio won't play his songs anymore? Go bluegrass! The Hag does for string-picking what he did for western swing on 1970's A Tribute To The Best Damn Fiddle Player In The World: Or, My Salute To Bob Willis. In "What Happened?" he pines for the days when America wasn't fueled by foreign cars, Wal-Mart and the evening news. This is no purist's bluegrass album, but rather an acoustic take on some of his previous songs and timeless standards. Marty Stuart shows up to play mandolin, and Alison Krauss harmonizes on "Mama's Hungry Eyes."
