No longer involved with alt-country giants the Jayhawks (he left in 2012 after an ugly falling out with co-leader Gary Louris) or the Original Harmony Ridge Creekdippers (they closed out a prolific seven-year run with their last album in 2004), Minneapolis native and bandana enthusiast Mark Olson has kept busy continuing his lifelong burrow into Americana traditions, releasing solo and duet records. Most recently, the 56-year-old has been recording and touring with his wife, Norwegian singer and multi-instrumentalist Ingunn Ringvold. Following 2014’s worldly Good-bye Lizelle, Olson and Ringvold released their second album together this September. Spokeswoman of the Bright Sun is a work of quiet, pastoral beauty that, like its predecessor, subtly incorporates a vast range of instrumentation, including dulcimer, mellotron, and strings. Following recent touring in the Netherlands, Ireland, and elsewhere, Saturday’s show at the Cedar is one of Olson’s two Minnesota concerts to close out the year, preceding a gig in Duluth next Wednesday.
