Tired of bland Celtic muzak and mushy New Age fusions? Want to hear some world music that’s inventive, exciting, and just a bit exotic? Then don’t miss this special one-night stand from the “Nordic Night Tour” featuring several of Scandinavia’s most innovative acts: Norway’s Annbjorg Lien Band, Sweden’s Vasen, and Finland’s JPP. An acknowledged master of the hardingfele, Norway’s national instrument, Ms. Lien is no purist. On her latest recording, Baba Yaga, she presents original compositions whose arrangements mix traditional-sounding melodies with everything from guttural throat singing to jazzy tempo shifts and electronic percussion. With only nyckelharpa, viola, guitar, and percussion, the members of Vasen—hot players who switch rhythms at a second’s notice—create amazingly full and varied textures. And JPP essays a unique chamber-folk sound built around fiddles, harmonium, and upright bass. The midnight-sun sounds begin at 8:30 p.m. at the Birchmere, 3701 Mount Vernon Ave., Alexandria. $15. (703) 549-7500. (Ken Roseman)
