full_context: Document 1: Anthrax (American band): Anthrax is an American heavy metal band from New York City, formed in 1981 by rhythm guitarist Scott Ian and bassist Dan Lilker. The group was considered one of the leaders of the thrash metal scene during the 1980s. Of the "Big Four" thrash metal bands (the others being Metallica, Megadeth and Slayer), Anthrax were the only band from the East Coast. As of April 2017, the band has released 11 studio albums, several other albums, and 26 singles, including collaborating on a single with American hip hop group Public Enemy. According to Nielsen SoundScan, Anthrax sold 2.5 million records in the United States from 1991 to 2004, with worldwide sales of 10 million.
Document 2: Symbol of Salvation: Symbol of Salvation is the fourth album by American heavy metal band Armored Saint. It was released in 1991 on Metal Blade Records and was their last album before going on an extended hiatus that would last until 1999. The songs on this album were written and demoed between 1988 and 1990 with original guitarist Dave Prichard (except "Truth Always Hurts"), who died of leukemia in 1990 prior to recording. The first guitar solo on "Tainted Past" was lifted from a 1989 4-track demo recorded by Prichard. The album was produced by Dave Jerden, who had produced Alice In Chains and Jane's Addiction albums beforehand. Jerden would go on to produce vocalist John Bush's first album with Anthrax, "Sound of White Noise" in 1993.

Document 5: Velocity Girl (song): "Velocity Girl" is a song by British alternative rock band Primal Scream, originally released as the B-side to their second single, "Crystal Crescent", in 1986. Shortly preceding its release, Primal Scream’s frontman, Bobby Gillespie, left his post as the drummer of The Jesus and Mary Chain, recording only one album with them, the influential noise pop release "Psychocandy" (1985). Disentangled from their major label "whirlwind", he resumed activity with the lesser known Primal Scream, proceeding to, as "Pitchfork Media" later described it, "reduce the pop song to its subatomic essence: quick, breezy, quirky, and above all, exquisitely small" with "Velocity Girl".
Document 6: Murray Dalglish: Murray Dalglish was the original drummer for The Jesus and Mary Chain from their formation in early 1984 until November 1984 when he was replaced by Bobby Gillespie. Aged 16 when he joined the band, Dalglish played a two-piece drum kit, which he did whilst standing up; this style would later be carried on in Gillespie's playing. His drumming can be heard on the band's first single "Upside Down", along with its B-side, the Syd Barrett cover "Vegetable Man". He was reportedly kicked out of the band as his father demanded that Dalglish be given more money, despite the fact that the band at the time was making little, if any, money at all.
