Bluegrass wasn't that popular when Donna the Buffalo started 30 years ago. Thanks to the popularity of bands like the Avett Brothers and Yonder Mountain String Band, it’s seen a resurgence in popularity. The band's latest album, Dance in the Street, emphasizes the jam band side of its sound. The title track features spoken word vocals and snappy percussion and the twangy "Motor" sounds like it could be a classic country tune. It might just be the band's most fully realized album. (Niesel)
