Maurice de Jong, known as Mories, born on September 5, 1973, in Paramaribo, Suriname, is a Dutch composer and musician. He began performing with bands in 1988, influenced by black metal, death metal, and doom metal. In the early 1990s, de Jong performed with Cauteror and Soulwound, emphasizing a depressing atmosphere in their lengthy songs. His solo project Astral, inspired by Necromantia, omitted electric guitars, focusing on bass guitar compositions. He later founded Ophiuchus in 1996, which was revitalized as Cloak of Altering in 2010. In 2004, he started Gnaw Their Tongues, with notable releases like An Epiphanic Vomiting of Blood (2007) and L'arrivée de la terne mort triomphante (2010). Gnaw Their Tongues began live performances in 2015.
