Smoke on the Water (5-Part Flexible Band and Opt. Strings) (HL Flex-Band) One of the tried and true rock anthems of the 70s, this gritty Deep Purple classic will be a blast to perform. 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.
