question: In what year was the heavy metal band who wrote the song Guarded formed?
answer: 1996
context: Title: Heavy metal bass
  Passage: Heavy metal bass is the use of the bass guitar (also called "electric bass") in the rock music genres of heavy metal and hard rock.  The bassist is part of the rhythm section in a heavy metal band, along with the drummer, rhythm guitarist and, in some bands, a keyboard player.  The prominent role of the bass is key to the metal sound, and the interplay of bass and distorted electric guitar is a central element of metal.  The bass guitar provides the low-end sound crucial to making the music "heavy".  The bass plays a "...more important role in heavy metal than in any other genre of rock."
  Title: Obús
  Passage: Obús is a Spanish heavy metal band created in Madrid in the early 80s.  They stood out because they took the risk of making a big spectacle in their concerts in order to reach to the level of other international heavy metal bands.  In addition, the lyrics they write and the feelings they transmit connect with the people that follow them.  As they said in an interview: "All our songs , some more and some less, have a meaning".  Far away from renouncing to their genre, they have always claimed that they were a heavy metal band and they even wrote a song about this genre in their first LP called"Dosis de Heavy Metal". In 2012, because of their 30th anniversary, they did a Tour around Spain.
  Title: Darkthrone
  Passage: Darkthrone is a Norwegian heavy metal band.  It formed in 1986 as a death metal band under the name Black Death.  In 1991, the band embraced a black metal style influenced by Bathory and Celtic Frost and became one of the leading bands in the Norwegian black metal scene.  Their first three black metal albums—"A Blaze in the Northern Sky", "Under a Funeral Moon" and "Transilvanian Hunger" (sometimes dubbed the "Unholy Trinity") — are considered the peak of the band's career and to be among the most influential albums in the genre.  For most of this time, Darkthrone has been a duo of Nocturno Culto and Fenriz, who have sought to remain outside the music mainstream.  Since 2006, their work has strayed from the traditional black metal style and incorporated more elements of traditional heavy metal, speed metal and punk rock, being likened to Motörhead.
  Title: Jesters of Destiny
  Passage: Jesters of Destiny is a heavy metal band from Los Angeles, California, which was formed in 1984 by Bruce Duff (bass/vocals, who had been booted from 45 Grave earlier in the year) and guitarist Ray Violet.  Evolving from a recording project spearheaded by Violet, who was working as the house engineer for Dawnbreaker studio in San Fernando, CA (previously owned by Seals and Crofts), the band recorded what would be the first two Jesters songs during the project,which was instigated in order to come up with commercial jingles.  The songs were "Diggin' That Grave" and "End of Time."  The band presented the songs to Metal Blade Records, who included "End of Time" on Metal Massacre V collection.  It closed the LP, which include early tracks by Overkill, Fates Warning, Voi Vod and Metal Church.  The band then signed to Metal Blade, but due to the band not being strictly heavy metal, the label created a subsidiary, Dimension Records, which released the band's debut album, "Fun at the Funeral", in 1986, and an EP, "In a Nostalgic Mood", in 1987, during their first tenure.  Following ",,"Mood,"" Metal Blade dropped the band.  They demo-ed a number of songs for a planned third LP to be titled, "No Laughing Matter," but we're unable to land a new recording contract.

  Title: Heavy metal lyrics
  Passage: Heavy metal lyrics are the words used in songs by heavy metal artists.  Given that there are many genres of heavy metal, it is difficult to make generalizations about the lyrics and lyrical themes.  In 1989, two metal scholars wrote that heavy metal lyrics concentrate "on dark and depressing subject matter to an extent hitherto unprecedented" in any form of popular music.  Jeffrey Arnett states that metal songs are "overwhelmingly dominated" by "ugly and unhappy" themes which express "no hope" for the future.  Deena Weinstein has proposed one way to analyze metal song themes is loosely grouping them into two categories: the Dionysian theme (a reference to the Roman God of wine), which celebrates "sex, drugs and rock and roll", partying, and enjoyment of life and the Chaotic theme, which involves dark subjects such as Hell, injustice, mayhem, carnage and death.  Not all metal genres fall into Weinstein's two theme model; for example power metal's lyrical themes often focus on fantasy and mythology, camaraderie and hope, personal struggles and emotions, among other themes.  Another exception is pop metal bands, which replaced "gloom and doom" themes with "positive, upbeat" songs about romantic love and relationships, part of their goal of appealing more to female listeners.  In metal overall, the small number of metal songs about relationships are typically about unions that have "gone sour" long ago.
  Title: Kurdt Vanderhoof
  Passage: Kurdt Vanderhoof (born June 28, 1961) is an American guitarist, best known as the lead guitarist and founding member of the American heavy metal band Metal Church.  As early as 1976, in Aberdeen, Vanderhoof was ardently networking with local musicians and had formed a band called Tyr, which included Kirk Arrington on drums and Vanderhoof on rhythm guitar.  In 1978 Vanderhoof joined Seattle hardcore punk band The Lewd adopting the stage name "Blobbo" on bass guitar, switching instruments to guitar the following year.  The Lewd relocated from Seattle to San Francisco in 1980.  Following Vanderhoof's departure from The Lewd he formed Metal Church, named after a nickname given to his San Francisco apartment.  Vanderhoof moved back to his hometown, Aberdeen, Washington, with a vinyl single of Trash Can Baby as proof of his interlude with the Lewd.  In the summer of 1982, he formed a heavy metal cover band named Shrapnel.  It consisted of Tom Weber on drums, Duke Erickson on bass (both from Hoquiam), Mike Murphey ("muff", from Montesano) and a guitar player Vanderhoof had jammed with in high school(Aberdeen).  Shrapnel played four events to warm up, including a frat party at Pacific Lutheran University, after which the other guitar player quit, having had a religious experience, unwilling to cover The Number of The Beast by Iron Maiden.  His part was replaced by Craig Wells of Aberdeen, and Tom was eventually replaced by Kirk Arrington (also from Hoquiam) on drums.  When Mike Murphy left the band, they recruited David Wayne for vocal duties.  By 1983, Shrapnel had renamed itself to Vanderhoof's original band name, Metal Church.
