Progressive Bluegrass
Progressive bluegrass keeps the acoustic string-band instrumentation but opens it up to outside influences — jazz harmony, rock songwriting, extended improvisation, and unconventional song sources. Arrangements feature longer instrumental passages, more chromatic and modal harmony, occasional non-traditional instruments, and material drawn from pop, folk, and contemporary writers. The vocals retain bluegrass tightness but soften the hard "high lonesome" edge, favoring a more contemporary, accessible delivery.
History
Progressive bluegrass emerged in the late 1960s and early 1970s as younger players raised on rock and folk pushed the boundaries set by Monroe. The Country Gentlemen and the Osborne Brothers led the way by covering Bob Dylan and pop tunes, while New Grass Revival, the Seldom Scene, and J.D. Crowe & the New South fully embraced extended jams, electric bass on occasion, and adventurous repertoire. The movement legitimized experimentation within the form, paving the way for newgrass and jamgrass, and its alumni — Sam Bush, Béla Fleck, Jerry Douglas, Tony Rice — became the dominant instrumental voices of modern acoustic music.
