=== Progressive bluegrass ===
The group [[The Country Gentlemen]] is credited with starting the progressive bluegrass movement with their 1960 album ''[[Country Songs, Old and New]]'',<ref>{{Cite journal |date=2005-04-01 |title=Homegrown music: discovering bluegrass |journal=Choice Reviews Online |volume=42 |issue=8 |pages=42–4555-42-4555 |doi=10.5860/choice.42-4555 |doi-broken-date=1 February 2025 |issn=0009-4978}}</ref> combining traditional ballads such as "The Little Sparrow," "Weeping Willow" and "Ellen Smith" with traditional bluegrass instrumentation and "bouncy" mandolin and banjo parts distinct from those of traditional players such as Monroe and Scruggs.

Due to the exposure traditional bluegrass received alongside [[Country music|mainstream country music]] on radio and televised programs such as the [[Grand Ole Opry]], a wave of young and not exclusively Southern musicians began replicating the genre's format on college campuses and in coffeehouses amidst the [[American folk music revival]] of the early 1960s. These artists often incorporated songs, elements and instruments from other popular genres, particularly rock and roll. Banjoist [[Earl Scruggs]] of [[Flatt and Scruggs]] had shown progressive tendencies since the group's earliest days, incorporating jazz-inspired banjo and bass duets and complex chord progressions that extended the genre's original rigid, conservative structure. In the late 1960s, Scruggs experimented on duets with saxophonist [[King Curtis]] and added songs by the likes of [[Counterculture of the 1960s|counterculture]] icon [[Bob Dylan]] to the group's repertoire, while bandmate [[Lester Flatt]], a [[Traditional bluegrass|traditionalist]], opposed these changes, resulting in the group's breakup in 1969.

[[New Grass Revival]] began utilizing electric instrumentation alongside songs imported from other genres to great popularity in the 1970s and 1980s, and the term "newgrass" became synonymous with "progressive bluegrass". It continued to evolve though the '80s and '90s, moving closer to folk and rock in some quarters and closer to jazz in others, while festivals such as the [[Telluride Bluegrass Festival]], RockyGrass in Lyons, Colorado, and [[MerleFest]] in [[Wilkesboro, North Carolina]] began to attract acts from outside the bluegrass tradition, merging the bluegrass community with other popular music scenes across America.

Following the death of [[Jerry Garcia]], who began his career playing bluegrass, and the dissolution of the [[Grateful Dead]], the blossoming "[[jam band]]" scene that followed in their wake embraced and included many groups that performed progressive bluegrass styles that included extended, exploratory [[musical improvisation]], often called "jamgrass." This style began to define many such acts whose popularity has grown into the 21st century, such as [[Leftover Salmon]], [[The String Cheese Incident]], [[Yonder Mountain String Band]], [[The Infamous Stringdusters]], [[Railroad Earth]], [[Greensky Bluegrass]] and [[Billy Strings]]. In recent years, groups like the [[Punch Brothers]], the [[Jon Stickley Trio]] and [[Nickel Creek]] have developed a new form of progressive bluegrass which includes highly arranged pieces resembling [[contemporary classical music]] played on bluegrass instruments. These bands feature complicated rhythms, chord schemes, and harmonics combined with improvised solos. At the same time, several popular [[indie folk]] and [[folk rock]] bands such as the [[Avett Brothers]], [[Mumford & Sons]] and [[Trampled by Turtles]] have incorporated rhythmic elements and instrumentation from the bluegrass tradition into their [[popular music]] arrangements, as has the [[Branson, Missouri|Branson]]-based band [[The Petersens]].
