February’s “Organ Plus” invites strings to accompany the Fritts Organ in Thomsen Chapel for an intimate performance. Local Pacific Northwestern musicians Una Hwang, organ, and Svend Rønning, violin, play a continental mix of Italian, French, and German music – a Vitali chaconne for violin, “Mélodie” from Gluck’s Orfeo, Bruhns’ Preludium in e minor, and chorale preludes for organ by J.S. Bach and French organist Jeanne Demessieux. The program will begin with “Winter” from Vivaldi’s The Four Seasons.
