Warner Bros. Records Inc. is an American record label. It was the foundation label of the present-day Warner Music Group, and now operates as a wholly owned subsidiary of that corporation. It maintains a close relationship with its former parent, Warner Bros. Pictures, although the two companies... are independently owned. Rob Cavallo currently serves as Chairman of the company. Warner Bros. Records was originally established in 1958 as the recorded music division of the American movie studio Warner Bros. Pictures. For most of its existence it was one of a group of labels owned and operated by larger parent corporations. The sequence of companies that controlled Warner Bros. and its allied labels evolved through a convoluted series of corporate mergers and acquisitions from the early 1960s to the early 2000s. Over this period, Warner Bros. Records grew from a struggling minor player in the industry to become one of the top recording labels in the world. In 2003 these music assets were divested by their then owner Time Warner and purchased by a private equity group. This independent company traded as the Warner Music Group , before being bought by Access Industries in 2011.

Heavy metal is a genre of rock music that developed in the late 1960s and early 1970s, largely in the Midlands of the United Kingdom and in the... United States. With roots in blues rock and psychedelic rock, the bands that created heavy metal developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Heavy metal lyrics and performance styles are generally associated with masculinity and machismo. The first heavy metal bands such as Led Zeppelin, Black Sabbath and Deep Purple eventually attracted large audiences, though many were critically reviled , 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; Motörhead introduced a punk rock sensibility and an increasing emphasis on speed. Bands in the New Wave of British Heavy Metal such as Iron Maiden followed in a similar vein. Before the end of the decade, heavy metal fans became known as "metalheads" or "headbangers".

Rock music is a genre of popular music that developed during and after the 1960s, particularly in the United Kingdom and the United States. It has... its roots in 1940s and 1950s rock and roll, itself heavily influenced by rhythm and blues and country music. Rock music also drew strongly on a number of other genres such as blues and folk, and incorporated influences from jazz, classical and other musical sources. Musically, rock has centered around the electric guitar, usually as part of a rock group with bass guitar and drums. Typically, rock is song-based music with a 4/4 beat utilizing a verse-chorus form, but the genre has become extremely diverse and common musical characteristics are difficult to define. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political in emphasis. The dominance of rock by white, male musicians has been seen as one of the key factors shaping the themes explored in rock music. Rock places a higher degree of emphasis on musicianship, live performance, and an ideology of authenticity than pop music.

Pop music is a genre of popular music which originated in its modern form in the 1950s, deriving from rock and roll. The terms popular music and pop... music are often used interchangeably, even though the former is a description of music which is popular , whilst the latter is a specific genre containing qualities of mass appeal. As a genre, pop music is very eclectic, often borrowing elements from other styles including urban, dance, rock, Latin and country; nonetheless, there are core elements which define pop. Such include generally short-to-medium length songs, written in a basic format , as well as the common employment of repeated choruses, melodic tunes, and catchy hooks. So-called "pure pop" music, such as power pop, features all these elements, utilising electric guitars, drums and bass for instrumentation; in the case of such music, the main goal is usually that of being pleasurable to listen to, rather than having much artistic depth.
