Progressive Bluegrass

Progressive bluegrass, often called newgrass, is a development of bluegrass that emerged in the late 1960s and 1970s as younger players extended the music beyond its traditional repertoire and forms. It retains the acoustic string-band lineup and virtuoso picking of bluegrass but admits material from rock, jazz, folk, and pop, longer improvisational passages, electric instruments on occasion, and harmonies and song structures foreign to the Monroe tradition. The style was codified by the *New Grass Revival* and the solo work of its members, and it continues in contemporary string bands that treat bluegrass technique as a platform rather than a boundary.
