Power Metal

During the late 1980s, the power metal scene came together largely in reaction to the harshness of death and black metal. Though a relatively underground style in North America, it enjoys wide popularity in Europe, Japan, and South America. Power metal focuses on upbeat, epic melodies and themes that "appeal to the listener's sense of valor and loveliness." The prototype for the sound was established in the mid- to late 1980s by Germany's Helloween, which combined the power riffs, melodic approach, and high-pitched, "clean" singing style of bands like Judas Priest and Iron Maiden with thrash's speed and energy, "crystalliz[ing] the sonic ingredients of what is now known as power metal."

Traditional power metal bands like Sweden's HammerFall, England's DragonForce, and Florida's Iced Earth have a sound clearly indebted to the classic NWOBHM style. Many power metal bands such as Florida's Kamelot, Finland's Nightwish, 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.

Closely related to power metal is progressive metal, which adopts the complex compositional approach of bands like Rush and King Crimson. This style emerged in the United States in the early and mid-1980s, with innovators such as Queensrÿche, Fates Warning, and Dream Theater. The mix of the progressive and power metal sounds is typified by New Jersey's Symphony X, whose guitarist Michael Romeo is among the most recognized of latter-day shredders
