Other major bluegrass mandolinists who emerged in the early 1950s and are still active include Jesse McReynolds (of Jim and Jesse) who invented a syncopated banjo-roll-like style called crosspicking—and Bobby Osborne of the Osborne Brothers, who is a master of clarity and sparkling single-note runs. Highly respected and influential modern bluegrass players include Herschel Sizemore, Doyle Lawson, and the multi-genre Sam Bush, who is equally at home with old-time fiddle tunes, rock, reggae, and jazz. Ronnie McCoury of the Del McCoury Band has won numerous awards for his Monroe-influenced playing. The late John Duffey of the original Country Gentlemen and later the Seldom Scene did much to popularize the bluegrass mandolin among folk and urban audiences, especially on the east coast and in the Washington, D.C. area.
