Progressive metal
The origins of progressive metal started with progressive rock bands from the late 1960s and early to mid-1970s such as Yes, Pink Floyd, Jethro Tull, King Crimson, Genesis, Kansas and Rush. However, progressive metal did not evolve into a genre of its own until the mid-1980s. Bands such as Queensrÿche, Fates Warning and Dream Theater took certain aspects of progressive rock music and mixed them with heavy metal styles.
