The KSO literally trumpets, rockets and dances to open its 30th season on October 16, at Drees Homes Auditorium (St. Henry H.S.). This all-orchestral program features not the Three Bs (Bach, Beethoven and Brahms) but the New Bs —(Boyer, Bates and Bartok). Peter Boyer’s “New Beginnings” (2000) opens with a driving fanfare that gives way to a haunting lyrical melody and zippy, boisterous finish. The program triumphantly concludes with Béla Bartók’s 20th c. warhorse — Concerto for Orchestra (1945).
