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.
Arena rock Arena rock (known additionally by various names such as "AOR" or "album-oriented rock", "anthem rock", "corporate rock", "dad rock", "melodic rock", "pomp rock", and "stadium rock" ) is a style of rock music that originated in the mid-1970s. As hard rock bands and those playing a softer yet strident kind of pop rock became increasingly popular, groups creating material inherently designed for large audiences, arena rock developed from their use of more commercially oriented and radio-friendly sounds. The often highly-produced music, including both upbeat, dramatic songs and slower power ballads, features strong emphasis on melody and frequently employs anthemic choruses. Other major characteristics include prominent guitar effects and the use of keyboard instruments.
