Flatt and Scruggs are the other fathers of bluegrass. Earl Scruggs’ banjo playing—with his signature three-finger style—practically reinvented the instrument, while Lester Flatt’s singing and songwriting set a bedrock for the genre in the 1950s. Naturally, many of their greatest hits have stuck, and their repertoire remains constantly in rotation for modern bluegrass performers. From Carl Jackson to Tim O’Brien, Flatt and Scruggs’ music lives on well into the 21st century in the performances of the genre’s modern leaders.
