Destruction (band): 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.

ReliXIV: 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.
