Information:  - Dream Theater is an American progressive metal band formed in 1985 under the name Majesty by John Petrucci, John Myung, and Mike Portnoy while they attended Berklee College of Music in Boston, Massachusetts. They subsequently dropped out of their studies to concentrate further on the band that would ultimately become Dream Theater. Though a number of lineup changes followed, the three original members remained together along with James LaBrie and Jordan Rudess until September 8, 2010, when Portnoy left the band. In October 2010, the band held auditions for a drummer to replace Portnoy. Mike Mangini was announced as the new permanent drummer on April 29, 2011.  - Satan ("satan", meaning "enemy" or "adversary"; "shaitan", meaning; "astray", "distant", or sometimes "devil") is a figure appearing in the texts of the Abrahamic religions who brings evil and temptation, and is known as the deceiver who leads humanity astray. Some religious groups teach that he originated as an angel, or something of the like, who used to possess great piety and beauty, but fell because of hubris, seducing humanity into the ways of falsehood and sin, and has power in the fallen world. In the Hebrew Bible and the New Testament, Satan is primarily an accuser and adversary, a decidedly malevolent entity, also called the devil, who possesses abhorrent qualities. Although Satan is generally viewed as having negative characteristics, some groups have very different beliefs. In Theistic Satanism, Satan is considered a deity who is either worshipped or revered. In LaVeyan Satanism, "Satan" is a symbol of virtuous characteristics and liberty.  - Reign in Blood is the third studio album and the major-label debut by American thrash metal band Slayer. It was released on October 7, 1986, by Def Jam Recordings. The album was the band's first collaboration with record producer Rick Rubin, whose input helped the band's sound evolve. "Reign in Blood" was well received by both critics and fans, and was responsible for bringing Slayer to the attention of a mainstream metal audience. "Kerrang!" magazine described the record as "the heaviest album of all". Alongside Anthrax's "Among the Living", Megadeth's "Peace Sells... but Who's Buying?" and Metallica's "Master of Puppets", "Reign in Blood" helped define the sound of the emerging US thrash metal scene in the mid-1980s, and has remained influential since then.  - A record label or record company is a brand or trademark associated with the marketing of music recordings and music videos. Often, a record label is also a publishing company that manages such brands and trademarks, coordinates the production, manufacture, distribution, marketing, promotion, and enforcement of copyright for sound recordings and music videos; conducts talent scouting and development of new artists ("artists and repertoire" or "A&R"); and maintains contracts with recording artists and their managers. The term "record label" derives from the circular label in the center of a vinyl record which prominently displays the manufacturer's name, along with other information.  - Cannibal Corpse is an American death metal band from Buffalo, New York.

Initially termed "progressive pop", the style was an outgrowth of psychedelic bands who abandoned standard pop traditions in favour of instrumentation and compositional techniques more frequently associated with jazz, folk or classical music. Additional elements contributed to its "progressive" label: lyrics were more poetic, technology was harnessed for new sounds, music approached the condition of "art", and the studio, rather than the stage, became the focus of musical activity, which often involved creating music for listening, not dancing.  - RED Distribution, LLC (formerly Relativity Entertainment Distribution) is a Sony Music Entertainment-owned sales and marketing division that handles releases for more than sixty independent record labels.
