Ralph Stanley: Bluegrass musician, considered one of the founders of the genre. Banjo player. Along with his brother Carter, he formed the Stanley Brothers around the middle of the twentieth century, playing a rather more old-time mountain style than the other two major bluegrass groups of the period, Bill Monroe and the Blue Grass Boys and Flatt & Scruggs. When Carter died, Ralph continued playing, being still active well into the twenty-first century. He is known as the performer of "O Death" in the move "O Brother, Where Art Thou?"
