Songs for the Living is the fourth album by the Christian metal band Embodyment.
 The album was the biggest departure from the band's original Death metal/deathcore sound, the album being more of an Alternative metal.
Stoner rock or stoner metal is a rock music fusion genre that combines elements of heavy metal and/or doom metal with psychedelic rock and acid rock.
 The name references cannabis consumption.
 The term desert rock is often used interchangeably with the term "stoner rock" to describe this genre; however, not all stoner rock bands would fall under the descriptor of "desert rock".
 Stoner rock is typically slow-to-mid tempo and features a heavily distorted, groove laden bass-heavy sound, melodic vocals, and "retro" production.
 The genre emerged during the early 1990s and was pioneered foremost by the Californian bands Kyuss and Sleep.
Psychobilly is a rock music fusion genre that mixes elements of rockabilly and punk rock.
 TheFreeDictionary.com defines it as "loud frantic rockabilly music", while according to About.com it "takes the traditional countrified rock style known as rockabilly, ramp[ing] up its speed to a sweaty pace, and combin[ing] it with punk rock and imagery lifted from horror films and late-night sci-fi schlock...[creating a] gritty honky tonk punk rock."
 Dark imagery is also central to an offshoot of psychobilly known as gothabilly.
Deliverance is the 1989 self-titled debut album by the Christian speed/thrash metal band Deliverance.
 The original Intense Records pressing is now considered a valuable collectable.
 It was reissued, minus 2 songs in 1998 on KMG Records as a two-disc set along with the 1990 album "Weapons of Our Warfare".
 It was officially re-released late 2008 with 2 bonus tracks on Retroactive Records.
 The album was ranked at No. 44 on "Metal Hammer"' s top 50 thrash metal albums of all-time list.
 In 2010, "HM Magazine" listed "Deliverance" No. 31 on its Top 100 Christian Rock Albums of All Time list stating that "'If You Will' into 'The Call' is almost as good as metal gets (-Doug Van Pelt)" and that "this record would forever change and impact me and the Christian metal music scene as we knew it!"
(-Bill Balford).
 Heaven's Metal fanzine ranked it No. 3 on its Top 100 Christian metal albums of all-time list.
 About.com writer Dan Marsicano wrote "Metal with a religious concept is not for everybody, and Deliverance doesn’t try to pander to the secular crowd.
 So, if you don’t mind a little preaching, their music is straight-to-the-gut thrash metal at a time where the genre was getting more expansive with its themes and sound.
 For giving Christian metal a thrash hero to rally behind, Deliverance gets the nod for this week’s Retro Recommendation."
Gothic metal (or goth metal) is a fusion genre combining the heaviness of heavy metal with the dark atmospheres of gothic rock.
 The music of gothic metal is diverse with bands known to adopt the gothic approach to different styles of heavy metal music.
 The genre originated during the early 1990s in Europe originally as an outgrowth of death-doom, a fusion of death metal and doom metal.
 Lyrics are generally dark and introspective with inspiration from gothic fiction as well as personal experiences.
Garage punk is a rock music fusion genre combining punk rock and garage rock that took shape in the indie rock underground between the late 1980s and early 1990s.
 Bands drew heavily from stripped-down 1970s punk rock and Detroit proto-punk, and incorporated numerous other styles into their approach, such as power pop, 1960s girl groups and garage rock, hardcore punk, early blues and R&B, and surf rock.
Human Sacrifice is the first studio album by the Christian death and thrash metal band Vengeance Rising.
 It is the first full length Christian thrash metal album as it was released in 1988.
 Though controversial, "Human Sacrifice" and the following album, "Once Dead" were huge successes in the world of Christian music, making Vengeance Rising one of the few bands in the genre to cross over into the secular music scene.
 Dave Caughney of "Cross Rhythms" magazine wrote in 1990 that this "legendary classic debut [...] breathed much needed freshness into the somewhat stale white metal (Christian metal) scene". "
HM Magazine" editor Doug Van Pelt called "Human Sacrifice" "the most radical Christian album ever released".
 In 2010, HM ranked "Human Sacrifice" the best Christian metal album of all time on its Top 100 list because it "tilted the Christian metal world on its ear".
The Narrow Scope of Things is the second album by the Christian rock band Embodyment.
 It is the first album not to feature original vocalist Kris McCaddon or Rhythm Guitarist James Lanigan.
 It is also the first to completely abandon the band's previous death metal style, pursuing a more alternative rock style.
Alternative metal (also known as alt-metal) is a rock music fusion genre that infuses heavy metal with influences from alternative rock and other genres not normally associated with metal.
 Alternative metal bands are often characterized by heavily downtuned, mid-paced guitar riffs, a mixture of accessible melodic vocals and harsh vocals and sometimes unconventional sounds within other heavy metal styles.
 The term has been in use since the 1980s, although it came into prominence in the 1990s.
Burial is the first album by the Norwegian Christian metal band Extol.
 It was released on Endtime Productions and then Solid State Records the following year.
 According to Allmusic, "Burial" was "a breath of fresh air among a genre that relies on satanic gimmicks", and marked a renewal in the Christian metal scene.
 In 2010, "HM" magazine ranked it #13 on the Top 100 Christian metal albums of all-time list.
