Heavy Metal

Heavy metal (sometimes referred to simply as metal) is a genre of rock music that developed in the late 1960s and early 1970s. With roots in blues-rock and psychedelic rock, the bands that created heavy metal developed a thick, heavy, guitar-and-drums-centered sound, characterized by highly amplified distortion and fast guitar solos. The All Music Guide states that "of all rock & roll's myriad forms, heavy metal is the most extreme in terms of volume, machismo, and theatricality."
Heavy metal has long had a worldwide following of fans known as "metalheads" or "headbangers". Although early heavy metal bands such as Led Zeppelin, Black Sabbath, and Deep Purple attracted large audiences, they were often critically reviled at the time, a status common throughout the history of the genre. In the mid-1970s, Judas Priest helped spur the genre's evolution by discarding much of its blues influence; the New Wave of British Heavy Metal followed in a similar vein, fusing the music with a punk rock sensibility and an increasing emphasis on speed.
Heavy metal became broadly popular during the 1980s, when many now-widespread subgenres first evolved. Variations more aggressive and extreme than metal music of the past were mostly restricted to an underground audience; others, including glam metal and, to a lesser extent, thrash metal went on to mainstream commercial success. In recent years, styles such as nu metal have further expanded the definition of the genre. Link

The Pioneers: Led Zeppelin

Led Zeppelin were an English rock band that formed in September 1968. Led Zeppelin consisted of Jimmy Page, Robert Plant, John Bonham, and John Paul Jones. With their heavy, guitar-driven sound, Led Zeppelin are regarded as one of the first heavy metal bands. Their rock-infused interpretation of the blues also incorporated rockabilly, reggae, soul, funk, jazz, classical, Celtic, Indian, Arabic, folk, pop, Latin and country. The band did not release the popular songs from their albums as singles in Britain, as they preferred to develop the concept of album-oriented rock.
Over 25 years after disbanding following Bonham's 1980 death, Led Zeppelin continue to be held in high regard for their artistic achievements, commercial success, and broad influence. The band have sold more than 300 million albums worldwide, including 109.5 million sales in the United States.Led Zeppelin are ranked No. 1 on VH1's list of the 100 greatest artists of hard rock.

Black Sabbath

Black Sabbath are an English heavy metal[1][2] band from Birmingham. The original band line up of Ozzy Osbourne (vocals), Tony Iommi (guitar), Terence "Geezer" Butler (bass), and Bill Ward (drums) is the same as the current line up (2007) although there have been many shifts of personnel over the years.
Black Sabbath remain a dominant influence in the heavy metal genre they helped create.[3] VH1's 100 Greatest Artists of Hard Rock ranks them second, behind Led Zeppelin.[4]
Currently, the early 1980s line-up of the band featuring Iommi, Butler, Ronnie James Dio and Vinny Appice are touring under the moniker Heaven and Hell, a title taken from the 1980 Black Sabbath album of the same name. Link

Deep Purple

Deep Purple are an English hard rock band formed in Hertfordshire in 1968. Along with Led Zeppelin and Black Sabbath, they are considered one of the pioneers of heavy metal and hard rock, although the members of the band have always refused to label themselves as the former. They have sold over 100 million albums worldwide.
The band has gone through many line-up changes, as well as an eight years split and two reunions. Their second and most commercially successful line-up featured: Ian Gillan (lead vocals), Ritchie Blackmore (guitar), Jon Lord (keyboard), Roger Glover (bass guitar) and Ian Paice (drums). Link

Uriah Heep

Uriah Heep are an English rock band, formed in December 1969 when record producer Gerry Bron invited keyboardist Ken Hensley (previously a member of The Gods and Toe Fat) to join Spice, a band signed to his own Bronze Records label. Sometimes jokingly referred to as "The Beach Boys of heavy metal" for their melodic songs, and trademark multi-part harmony backing vocals, although their music draws on diverse influences including: progressive rock, hard rock, heavy metal, jazz and even country on occasion. In spite of their huge popularity in Britain and continental Europe, Uriah Heep were never able to break into the American market in a big way, with the exception of three hit songs, "Easy Livin' " from the 1972 album Demons and Wizards, "Sweet Lorraine" from the 1972 album The Magician's Birthday (a top ten album in Australia), and "Stealin' " from the 1973 release Sweet Freedom. The band released several commercially successful albums in the 1970s, including the seminal Uriah Heep Live (1973), but their audience declined during the 1980s, to the point where they became essentially a cult band in the US and UK. Uriah Heep maintain a significant following in Germany, the Netherlands, the Scandinavian Peninsula, the Balkan Peninsula, Japan and Russia, where they still perform at stadium-sized venues. Link

UFO

UFO are an English rock band formed in 1969. UFO became a transitional band between early hard rock and heavy metal and the New Wave of British Heavy Metal. UFO's influence was strongly felt in the 1980s heavy metal scene and they have been cited as a primary influence of Steve Harris of Iron Maiden, Kirk Hammett of Metallica and Dave Mustaine of Megadeth, Frank Hannon of Tesla among others.

The Next Generation: Iron Maiden

Iron Maiden are an English heavy metal band from east London. The band were formed in 1975 by bassist Steve Harris, formerly a member of Gypsy's Kiss and Smiler. Iron Maiden are one of the most successful and influential bands in the heavy metal genre, having sold 80 million albums worldwide.[1] The band won the Ivor Novello award for international achievement in 2002.[2]
The band have headlined several major events in its career, notably Rock in Rio, Ozzfest alongside Black Sabbath, Donington's "Monsters of Rock" and "Download" Festivals and the "Reading and Leeds Festivals."
Although Iron Maiden are a heavy metal band, influenced by Thin Lizzy and Deep Purple, their earlier music had punk overtones mainly due to vocalist Paul Di'Anno and punk rock's influence on NWOBHM-era heavy metal as a whole.
Iron Maiden's mascot, Eddie, is a perennial fixture in the band's horror-influenced album cover art, as well as in live shows. Eddie was drawn by Derek Riggs until 1992, although there have been various incarnations by numerous artists including Melvyn Grant. Eddie is also featured in a first-person shooter video game from the band, Ed Hunter, as well as numerous books, graphic comics and band-related merchandise. Link
