The history of coffee consumption in 20th century America takes hold in the small cafes, truck stops and coffeehouses which became venues and social spaces for the community. Like music, they helped with the congregation of like minds and served as hubs for intellectual exchange, artistic expression and social activism. And it was all because of the caffeine. Instant and decaf coffees were just an aberration; much like disco. This week’s Deeper Roots drives the theme of coffee home with tracks that span the century including Emmett Miller, the King Cole Trio, The Bobs, Ella Mae Morse and Merle Travis (among others) to tell us a cuppa tale or two. It's one more Friday show ahead of next week’s 420 observation…one more libation to celebrate.
