Yonder Mountain String Band retains its traditional bluegrass sound on “The Show,” but the Colorado-based quartet has widened its commercial appeal by incorporating elements of rock and punk. Straying from the usual string accord of past albums, the band emphasizes its latest addition, drummer Pete Thomas (from Elvis Costello & the Imposters)-the song “Complicated” showcases a percussion-heavy sound previously unknown to Yonder fans. “Honesty” is another instrumentally commendable track, clocking in at more than eight minutes long. The blend of instruments and vocals will translate well into live performances, particularly with “Belle Parker” and “Fingerprints,” which double as radio-friendly tracks. Although Yonder doesn’t stray lyrically from its standard she-devil gripes, it successfully bends musical expectations and delivers a powerfully varied instrumental experience. –Samantha Hayden
