Detestation is the debut album by Japanese hardcore punk band G.I.S.M.

[1] The album has had a very large impact across numerous musical scenes, and its songs have been covered by many notable hardcore punk and extreme metal bands, including Poison Idea, Integrity, and Extreme Noise Terror.

Due to the cult status and the scarcity of the original record, it was up until 2020 one of the most bootlegged records of all time, and had only seen one official reissue in 1992 on Compact Disc on Sakevi Yokoyama's label Beast Arts.

While the bass and drums stylistically resemble standard hardcore punk, Randy Uchida's flashy and melodic guitar work, reminiscent of traditional heavy metal such as Iron Maiden, sets it apart from the typical punk rock format.

[2] The lyrics, which are penned by Sakevi and often feature broken English, depict violent illustrations of war - this theme can also be found in his notorious P.O.W.
