Like his contemporary Vassar Clements, fiddler Byron Berline expanded the sonic possibilities of bluegrass, adding elements of jazz, pop, blues, rock, and traditional country to the genre. In addition to being a popular solo act, he performed as a session musician on a number of albums, including records by the Flying Burrito Brothers, Stephen Stills, the Dillards, Gram Parsons, the Nitty Gritty Dirt Band, Emmylou Harris, Kris Kristofferson, and James Taylor.
