Prog metal for short. A sub genre of music that combines the almost jazz-like progression of progressive rock and the agression, volume, speed, and heaviness of metal. Usually features band members who are incredibly skilled at their instruments. Features rapid key changes, odd time signatures, and bombastic instrumental sections. It could be defined as "intelligent metal".
Rapid changes in key are a characteristic of progressive metal.
