Instrumental Weekend will fill Concordia University's chapel with Big Band favorites on Friday and Saturday, April 12-13, which will also feature a violin concerto solo by senior Emma Ledford. Friday's concert features The Jazz Ensemble and the University Band, while The Symphonic Wind Ensemble and Chamber Orchestra will perform at Saturday's event. Longtime music department chairman and Mequon resident Dr. Louis Menchaca directs both ensembles. Ledford will become the first CUW student to perform a portion of Felix Mendelssohn's 27-minute Violin Concerto Opus No. 64.
