Aztec Fire (5-Part Flexible Band and Opt. Strings) (HL Flex-Band) Here is a bold work with plenty of Latin excitement and drive. Contrast is provided in the melodic middle section, then the piece roars to a powerful conclusion. Hal Leonards innovative Flex-Band series is designed to provide exciting music for bands with incomplete or unbalanced instrumentation. Written using just five parts (plus percussion), these arrangements will work with virtually ANY combination of brass or woodwinds - even strings.
