Quirks—a word defined as a sudden sharp turn or an unpredictable peculiarity of behavior or action—demonstrates the capricious nature of the title in its musical character. The music vacillates between fast and slow, happy and sad, extroverted and introverted, and just never goes where you expect. There is plenty of interplay between winds and percussion as the four and three notes of the main motive are tossed about the many instrumental colors. This is a tour-de-force, destined to become a band standard for more advanced bands. You must give this a careful listen.
