Baroque violinist Karen Walthinsen began her career in the Pacific Northwest of the United States as a tenured member of the Spokane Symphony and music history and theory instructor at Eastern Washington University. After choosing to specialize in early music, she began studying the Baroque violin with John Holloway in Dresden, Germany, and with Elizabeth Wallfisch at the Royal Conservatory in The Hague, Netherlands. Since 2001 she has been a member of Les Musiciens du Louvre which tours and records extensively under the direction of Marc Minkowski. She regularly concertizes and records with other European ensembles including Cantus Cülln, Kölner Akademie, Camesina Quartett, Collegium Cartusianum, Neue Düsseldorfer Hofmusik, La Scintilla, Das Kleine Konzert and La Stagione Frankfurt. She is a founding member of the new period-instrument chamber ensemble, Mille Feuilles, which recently made its debut in Zürich, Switzerland. In addition to violin, Ms. Walthinsen plays Baroque viola and Medieval fiddle with Boston Camerata and Musica Fiata and is active in the area of musicology.
