For nearly 17 years, Yonder Mountain String Band has redefined bluegrass music, expanding the traditional acoustic genre beyond its previously established boundaries by steadily pushing the envelope into the realms of rock n' roll and improvisation. The result is music that doesn't stand still, it's always progressing and breaking unprecedented ground. With their latest album, Black Sheep, Yonder Mountain String Band - Adam Aijala, Dave Johnston, Ben Kaufmann, Allie Kral, and Jacob Jolliff - begins a new era. The first YMSB release produced by the band itself, Black Sheep is, by any measure, a triumph, perhaps the most mesmeric of their career. The result, says Kaufmann, is that, "This record sounds more like Yonder than any record we've ever done. I'm hoping that when people are finished listening to it, they'll just hit play and listen to it again."
