The Bozeman Symphony Chamber Orchestra performs at Willson Auditorium on February 2nd and 3rd. Surprises abound in this classy program for chamber orchestra. The elegance (and bustle) of Mozart’s Ballet Music from Idomeneo opens the program. Next, one of the great mysteries in all of music—Schubert’s hauntingly sublime Unfinished Symphony. We’ll conclude with Haydn’s famous Symphony No. 94 in G major, better known as the Surprise Symphony.
