Question: Infernal Overkill is the first full-length album by a band that was originally named what?
Context: Eternal Devastation is the second full-length album by German thrash metal band Destruction.  It was released in 1986.  It showed the band had moved away from their previous black metal-influenced style of material evident on the "Sentence of Death" EP and "Infernal Overkill" albums, and were headed in the direction of a more contemporary thrash metal style. Destruction is a German thrash metal band.  They have been referred to as one of the "Big 4" of the German thrash metal scene, the others being Kreator, Sodom and Tankard.  Along with Venom (UK), Bathory (Sweden) and Celtic Frost (Switzerland), three of those four German bands (Tankard being the exception) are often credited with helping pioneer black metal, by containing several elements of what was to become the genre.  Destruction was originally named Knight of Demon, but changed their name in 1984.  For most of the 1990s, Destruction was not signed to a record label and was forced to self-produce their albums until they signed a contract with Nuclear Blast in the early 2000s.

They released a 7" on Elkion Records titled "The Hits Just Keep on Comin" and shortly after signed a deal to Equal Vision Records and released their debut album "Masquerade in the Key of Crime" in the summer 2000.

In the summer of 2001 the band parted ways with vocalist John Johansen.  2002 saw the release of "Jungle City Twitch".  Debuting a new sound, The Stryder continued to tour the country in support of the new release.  In 2003/2004, Elkion Records released "Savor The Danger" which contained a collection of old demos and the 2 songs from the 7" previously released on the label.  Peter released his first solo EP "Cleopatra" in 2004 on Elkion Records.  Durijah moved on to become the drummer of Classic Case and in 2007, became Pete Parada's replacement in Saves The Day.  In 2006, Peter then went on to start an Internet TV/New Media Company, Hidden Track TV with Adam Schleichkorn, and released a solo EP titled "Shoes of a Beast".  Peter is currently working on his first full-length album, titled "Wildlife".  Scottie Redix now plays under the moniker 'Cassonova Brown' and is currently working on his first full-length.

Wrecking Your Neck is a 2-disc live album released by the thrash metal band Overkill in 1995.  A March 1995 show, once again in Cleveland, Ohio, was recorded for Overkill's first full-length live album, and was released in April 1995; with the first pressing featuring a bonus CD containing the "Overkill EP" that had been out of print for ten years.  A music video for the song "Bastard Nation" was also released.  "Wrecking Your Neck" is also the last Overkill album to feature guitarists Rob Cannavino and Merritt Gant. Earl Greyhound is an American rock trio from Brooklyn consisting of Matt Whyte (vocals, guitar), Kamara Thomas (bass, keyboards, vocals) and Ricc Sheridan (drums).  Sheridan replaced original drummer Christopher Bear just after the band recorded its first full-length album.  They were previously signed to Some Records but have since started their own label, Hawk Race Records.  Their music is heavily influenced by blues rock and hard rock bands of both the 1990s and the 1970s, and the intertwined vocals of Whyte and Thomas are a key component of the band's sound.  After an EP in 2004, the band's first full-length album, "Soft Targets", was released in 2006, followed by "Suspicious Package" in 2010. Separated Vegetables is the first full-length album by Washington, D.C.'s Slickee Boys.

As well as songs written by the band, it includes cover versions of songs originally by Overkill (an early D.C. punk band, not the heavy metal band of the same name), Flamin' Groovies, the Road Runners, Johnny Smith, Country Joe and the Fish, the Small Faces, Chuck Berry, and the Hangmen (whose song, "What a Girl Can't Do", the Slickee's had already released on their debut record, 1976's "Hot and Cool" EP.

In 2005, the band released their first full-length album "Kezia" on Canadian indie label Underground Operations. ReliXIV is the thirteenth full-length studio album by American thrash metal band Overkill, released in spring 2005.  The reason the Roman numeral 14 is included in the title is because the band includes the "Overkill EP" in their lineup of studio albums, which would make this album the 14th by their chronology.  It can also be because Overkill released the covers album "Coverkill", which would have been their eleventh studio album.  While this diction left it unclear how the title was to be pronounced, Blitz just mentioned it as "Relics" when announcing songs from the album on stage.  The album produced the popular "Old School", which has been played at every Overkill show since it was first released.  As of late 2007, ReliXIV sold over 16,000 copies in the U.S. The Maine is an American rock band from Tempe, Arizona, formed in 2007.
