Underestimated, but the roots of blues, folk, country and rock, and all others.

For the main entry for prog bluegrass is this track

I hope that we can increase the appreciation of the bluegrass here.

Very nice, that guy on slide plays a sweet ax, reminds me of Uli Roth.

Bluegrass 

Bluegrass music is a genre of American roots music that developed in the 1940s in the United States Appalachian region. The genre derives its name from the band Bill Monroe and the Blue Grass Boys. Unlike mainstream country music, bluegrass is traditionally played on acoustic stringed instruments. Bluegrass has roots in traditional English, Scottish and Irish ballads and dance tunes, and in traditional African-American blues and jazz. Bluegrass was further developed by musicians who played with Monroe, including 5-string banjo player Earl Scruggs and guitarist Lester Flatt. Monroe characterized the genre as: "Scottish bagpipes and ole-time fiddlin'. It's Methodist and Holiness and Baptist. It's blues and jazz, and it has a high lonesome sound."

Bluegrass features acoustic stringed instruments and emphasizes the off-beat. Notes are anticipated, in contrast to laid back blues where notes are behind the beat, which creates the higher energy characteristic of bluegrass. In bluegrass, as in some forms of jazz, one or more instruments each takes its turn playing the melody and improvising around it, while the others perform accompaniment; this is especially typified in tunes called breakdowns. This is in contrast to old-time music, in which all instruments play the melody together or one instrument carries the lead throughout while the others provide accompaniment. Breakdowns are often characterized by rapid tempos and unusual instrumental dexterity and sometimes by complex chord changes.

Progressive Bluegrass

Progressive bluegrass is a type of bluegrass music which became popular in the 1960s and 1970s and now the 2020s. The four important elements (not always all present) of progressive bluegrass are instrumentation (usually including electric instruments, drums, piano, and more), songs imported or styles imitated from other musical genres (like jazz, rock and others), non-traditional chord progressions, and lengthy "jam band"-style improvisation.

and another take of a kind of Bluegrass with other elements - Punch Brothers

and just for fun 

I am quite new to this genre and a blurry one it is. 

Feel free to post any Bluegrass prog orientated songs you may find, if you wish of course 

ANY Bela Fleck solo or with the Flecktones

Really enjoyable video. Thanks Sillypuppy. I have listened to Bela Fleck before but now with a new found appreciation. 

"Here and Heaven" are safely on the edge of prog leaning bluegrass music and right up my alley 

great track

Thanks, I listened to the first Seatrain album today and they do touch on the bluegrass or country roots, sound more a fusion band but that was popular at that time 1970s with a bit of gospel and a finale of crazy fiddle playing.  

This one is live at Redrocks with Greensky Bluegrass this past September
