Your average music listener might assume that metal bands are all the same in the instrument department—guitar, drums, bass, maybe piano or keyboards—but what about the flute, didgeridoo, saxophone, trumpet, lute, bagpipes, fiddle, berimbau, Whamola, or hurdy gurdy? As unlikely as it seems, there are metal bands that incorporate less mainstream instruments into their sound. Apocalyptica, for example, is comprised of four cellists and a drummer. Among folk, progressive, avant garde, and experimental metal subgenres (and even some mainstream acts), listeners can find all sorts of neat uses of unusual instrumentation. We’re going to share ten of our favorite “nontraditional” metal songs with you—see if you can guess what the instruments are!
