Born in the mid-20th century, bluegrass defies time, drawing inspiration from the past while also openly embracing progressive innovation. Inspired by vintage bluegrass concert posters, the stamp art features four acoustic string instruments typical of bluegrass bands: guitar, five-string banjo, fiddle, and mandolin. At once rural and urban, emotional and highly technical, this singular American music style remains unconstrained by geography, attracting fans worldwide who all share the same passion for what they affectionately call the “high lonesome sound.” Music: Not Drunk by the Joy Drops.
