Power metal
Traditional power metal bands like Sweden's HammerFall, England's DragonForce, and America's Iced Earth have a sound clearly indebted to the classic NWOBHM style. Many power metal bands such as America's Kamelot, Finnish groups Nightwish, Stratovarius and Sonata Arctica, Italy's Rhapsody of Fire, and Russia's Catharsis feature a keyboard-based "symphonic" sound, sometimes employing orchestras and opera singers. Power metal has built a strong fanbase in Japan and South America, where bands like Brazil's Angra and Argentina's Rata Blanca are popular.
