Any artist who's in it for the long haul is bound to weather changes and collect experiences over time. And when enough history builds up behind them, they may feel the irresistible tug of nostalgia and find ways to revisit the past — with songs idealizing the "old home place," albums of time-tested standards, lavishly packaged reissues or anniversary tours. Those reflections on the bygone days tend to be reverent affairs.

No music scene is monolithic, but few encompass the extremes of the bluegrass world. Both musically and ideologically, it runs the gamut from conservatism to progressivism, a range of sensibilities that it's rare to see commingling elsewhere in American society at this polarized moment.

Bobby Osborne is trying to find his way back to the lakeside home where he first heard "Rocky Top," the song that would define his career as one half of the Osborne Brothers, one of bluegrass' most popular and innovative groups.

For decades now, country's aesthetic and ideological sensibilities have been shaped as much by the music's modern, middle-class suburban appeal as its rural working-class roots, which can make for quite the rhetorical push-and-pull (likely one of many factors that contributed to the Dixie Chicks' famed expulsion from the format over voicing distaste for the second President Bush during a U.K. concert). Working-class political speech hasn't always been recognized as political at all; it's just as likely to be dismissed as class resentment.

Dan Tyminski might have one of the most recognizable voices in acoustic music. He grew up in southern Vermont, fixated on traditional bluegrass and old country. While his friends were buying Def Leppard and AC/DC records, he was playing banjo.
