They are called Seldom Scene, but they’re one of the most often heard bluegrass bands of the past 40 years. Formed in 1971, the Seldom Scene transformed Bill Monroe’s music of the 1940s and ’50s into a spirited blend of traditional and modern styles. Adapting folk and rock to Monroe’s storied bluegrass, along with sophisticated stage humor, the Scene expanded the music’s popularity from rural to urban audiences and contributed to a second wave of bluegrass interest. While the band’s lineup has changed through the years, founding member Ben Eldridge leads the award-winning quintet into Carrboro’s ArtsCenter Friday night for a show that promises to be one of the highlights of this year’s concert season.
