The second concert of the ASO's Masterworks series brings together three pieces that jump around in time. It begins with Haydn, one of the most prolific composers of the Classical period, and his energetic Symphony No. 9, the "Fire" Symphony. Next is the Lucent Variations of Michael Torke, who is currently one of the world's foremost American composers. The show concludes with Brahms' Concerto for Piano No. 1 in D Minor, which, according to conductor Phillip Mann, strikes fear in the heart of pianists; but not virtuoso Norman Krieger, who joins the symphony as soloist. The concert returns on Sunday at 3 p.m., when all kids high school age and younger can attend for free.
