According to Young, the music on Fascination was a progression for the band, and a challenge for them. Comparing their prior work to the new album, she said, "They're probably a bit more bluegrass-influenced than this one here. While we still have the bluegrass and roots music influences, we really wanted to push ourselves harder on this one, something a bit more challenging to play live." She described their music through their fourth album as having evolved, explaining that it began as traditional roots and bluegrass, but after six years is "our own little sound". The track "The Crystal Merchant" was nominated for the Grammy Award for Best Country Instrumental Performance.
