1972 John Boorman's film DELIVERANCE features a version of Reno and Smith's "Feudin' Banjos" called "Duelin' Banjos." The Newgrass Revival's first record is released. The band's longhaired, hippie appearance and use of electric instruments, as well as elements of jazz and rock music, are an assault on bluegrass convention, reaffirming the already present tension between tradition and evolution in the music of the Country Gentlemen, John Hartford, David Grisman, the Seldom Scene, and other bluegrass performers. 1974 The GRAND OLE OPRY moves from Ryman Auditorium in downtown Nashville, TN, where it has been staged since 1943, to a multi-million dollar entertainment complex in the suburbs that is part of the Opryland theme park. 1975 J.D. Crowe, a veteran banjo picker who has played with Jimmy Martin, among others, releases J.D. CROWE AND THE NEW SOUTH on Rounder with a new generation of bluegrass prodigies: Ricky Scaggs on mandolin, Tony Rice on guitar, Jerry Douglas on dobro, and Bobbly Sloane on fiddle and bass. The album is considered revolutionary for its tradition-minded renditions of songs by contemporary musicians as different as Gordon Lightfoot and Fats Domino. 1979 Lester Flatt passes away. 1985 The International Bluegrass Music Association (IBMA) is formed by music industry leaders. 1987 Alison Krauss, who won the Illinois State Fiddle Championship at age 12, releases her first album, TOO LATE TO CRY, on Rounder Records. Her success in the 1980s and 1990s is largely responsible for resurgence in bluegrass popularity. In 1995, her compilation, NOW THAT I'VE FOUND YOU A COLLECTION, goes to #2 on the country charts and hits the top ten on the pop charts. 1996 Bill Monroe passes away. 2000 The enormously (and unexpectedly) successful soundtrack to the Coen brothers' film O BROTHER, WHERE ART THOU?, featuring Alison Krauss, Ralph Stanley, John Hartford, Norman Blake, Gillian Welch, Emmylou Harris, and others, revives interest in bluegrass and traditional American folk music.
