Kaivama, by Kaivama

Lutheran rocker Jonathan Rundman is nothing if not prolific. Here he teams with violinist Sara Pajunen to form Kaivama, a folk music duo that yields tasty bluegrass instrumentals with a Finnish accent. Finland's Arto Järvelä plays strings on several tracks, including "Ruros," a plaintive, percussionless waltz. On the jauntier side, Rundman's "Edina Speedtrap" (named after his Minnesota hometown) is a sprightly mix of hoedown and Irish jig.
