Frigg with Kaivama

Fans of Finns, folk and fiddling won't want to miss this week's double bill of global stars Frigg, and local bright lights, Kaivama. Frigg is a seven-piece Finnish/Norwegian powerhouse, a rousing ensemble with violins, violins, and more violins, sawing away with mad contagious energy. Kaivama, colorfully self-described as "Finnish-American excavators," is the Twin Cities duo of Sara Pajunen and Jonathan Rundman. They recently released a gorgeous, beautifully-recorded and packaged self-titled debut CD. It features original tunes that sound deeply traditional ("Cross Country"), and authentic folk songs that seem both timeless and contemporary ("Pirun Polska"). Tom Surowicz
