Neoclassical metal Neoclassical metal is a subgenre of heavy metal that is heavily influenced by classical music and usually features very technical playing, consisting of elements borrowed from both classical and speed metal music. Deep Purple's Ritchie Blackmore pioneered the subgenre by merging classical melodies and blues rock. Later, Yngwie Malmsteen became one of the most notable musicians in the subgenre, and contributed greatly to the development of the style in the 1980s. Other notable players in the genre are Randy Rhoads, Jason Becker, Tony MacAlpine, Vinnie Moore, Uli Jon Roth, Stéphan Forté and Timo Tolkki.
Stoner rock Stoner rock or stoner metal is a rock music fusion genre that combines elements of heavy metal and/or doom metal with psychedelic rock and acid rock. The name references cannabis consumption. The term desert rock is often used interchangeably with the term "stoner rock" to describe this genre; however, not all stoner rock bands would fall under the descriptor of "desert rock". Stoner rock is typically slow-to-mid tempo and features a heavily distorted, groove laden bass-heavy sound, melodic vocals, and "retro" production. The genre emerged during the early 1990s and was pioneered foremost by the Californian bands Kyuss and Sleep.
