A band I like, the infamous stringdusters, recently and their wonderful mandolin player Jesse Cobb leave the band. After experimenting with a few other mandolin players, they have decided to proceed sans mandolin.
On another board I frequent a discussion broke out as to whether or not a band can really be considered "bluegrass" if there is no mandolin involved. For what little it's worth I say YES but am interested to hear other people opinions... especially those who know a lot more about music than me. Thought this would be an interesting place to ask.
