This is an incomplete list of heavy metal festivals.
 Heavy metal (or simply metal) is a genre of rock music that developed in the late 1960s and early 1970s, largely in the United States and the United Kingdom.
 With roots in blues rock and psychedelic rock, the first heavy metal bands such as Led Zeppelin, Black Sabbath and Deep Purple attracted large audiences, and during the late 1960s and mid-1970s these band and others in their genre were featured at a number of historic rock festivals. Judas Priest helped spur the genre's evolution by discarding much of its blues influence.
Kekal (sometimes stylized as KEKAL) is a heavy metal and electronic music band formed in 1995 in Jakarta, Indonesia.
 According to AllMusic, Kekal was one of the first heavy metal bands from Indonesia to make international inroads, and according to sociologist of heavy metal, Keith Kahn-Harris, was one of the few extreme metal bands from Southeast Asia to ever make more than a minimal impression on the global scene.
 Founded by two musicians known simply Yeris and Newbabe, the band underwent some shifts in lineup in its early years, but emerged with a consistent lineup of three key-members, guitarist/vocalist Jeff Arwadi, bassist Azhar Levi Sianturi, and guitarist Leo Setiawan.
 Frequently labeled as black metal, progressive metal, and avant-garde metal, Kekal plays a very diverse range of music styles within the frame of metal and rock, incorporating many other music genres such as ambient, electronic, jazz fusion, and progressive rock.
 Over the course of its career, Kekal has transitioned from a heavy metal-based style to a more experimental and electronic sound.
Daniel Alan Spitz (born January 28, 1963) is an American musician and watchmaker best known for his work as the lead guitarist, principal songwriter and co-producer of the American heavy metal band Anthrax from 1983 to 1995 and from 2005 to 2008.
 With Anthrax, Spitz was nominated for three Grammy awards and has been awarded platinum and multiple platinum RIAA certified albums for his entire Anthrax catalog of work.
 Dan Spitz is the first heavy metal songwriter to have his music playing on two planets.
 NASA chose his song alongside only 9 other artists such as Frank Sinatra and the Beatles to be played on the Lunar Rover Curiosity making him the first heavy metal artist to have a top 10 charting song on two planets.
 Spitz also founded the Christian music group Red Lamb alongside Dave Mustaine of Megadeth as his writing partner, the first to bring autism awareness into any genre of music or music video.
Black Sabbath is the debut album by the English rock band Black Sabbath.
 Released on 13 February 1970 in the United Kingdom and on 1 June 1970 in the United States, the album reached number eight on the UK Albums Charts and number 23 on the "Billboard" charts.
 Although it was poorly received by most contemporary music critics at the time, "Black Sabbath" is now widely considered the first heavy metal album.
Metal Health is the third studio album by American heavy metal band Quiet Riot.
 It was released on March 11, 1983, bolstered by the No. 5 hit "Cum On Feel the Noize" and the No. 31 hit "Metal Health".
 "Metal Health" is notable for being the first heavy metal album to reach the top spot on the "Billboard" 200, replacing the Police's "Synchronicity" at number one in November 1983.
 The album went on to sell more than six million copies and is considered a classic among heavy metal fans.
 Some critics, such as AllMusic, describe it as a one-hit wonder, owing to Quiet Riot's relative lack of critical and commercial success with following albums (and subsequent disintegration) towards the end of the 1980s.
 The title track was ranked No. 35 on VH1's 40 Greatest Metal Songs.

Event Horizon is the debut studio album by British heavy metal band I Am I, released in 2012.

 The album is quite melodic and a bit similar to the AOR of the 1970s and 1980s.
