Progressive bluegrass, also known as newgrass
(a term attributed to
New Grass Revival member Ebo Walker), is one of two
major subgenres of
bluegrass music. Progressive bluegrass came to
widespread attention in the late 1960s and 1970s, as some
groups began using electric instruments and importing songs
from other genres (particularly rock & roll), and important
groups from that period include the New Grass Revival,
J. D. Crowe and the New South, the Dillards, Boone Creek,
Country Gazette, and the Seldom Scene. However, progressive
bluegrass can be traced back to one of the earliest
bluegrass bands. A brief listen to the banjo and bass duets
Earl Scruggs played even in the earliest days of the Foggy
Mountain Boys give a hint of wild chord
progressions to come. The four key distinguishing elements
(not always all present) of progressive bluegrass are
instrumentation (frequently including electric instruments,
drums, piano, and more), songs imported (or styles imitated)
from other genres, non-traditional chord progressions, and
lengthy "jam band"-style improvisation.
Currently performing progressive bluegrass bands and musicians include the Czech band Druhá Tráva, bassist Missy Raines, and Alison Krauss and her band Union Station. Others who have been known to occasionally play progressive bluegrass include Béla Fleck and the Flecktones, and Nickel Creek.
