E.S. Posthumus是一支由两兄弟[Helmut＆Franz Vonlichten]，在2000年组成的独立组合。E.S.是“Experimental Sounds”的缩写，Posthumus的意思是“all things past”（逝者已矣），这乐队的名字就让人感觉很特别。音乐揉合交响乐及电子乐，加上鼓乐强劲节奏，气势滂薄，亦具史诗式的古典美。 　　乐队的兄弟二人，从小就和他们的妈妈学习钢琴。高中毕业后，Franz在录音室工作，而Helmut就读于洛杉矶加利福尼亚大学并获得考古学学位。 　　逝去的实验声的音乐经常被电视以及电影录用，为影视作品增色不少。 　　Career 　　The group was formed in 2000 by brothers Helmut and Franz Vonlichten. Helmut and Franz studied piano with their mother. After graduating from high school, Franz worked in recording studios while Helmut attended and graduated from UCLA, with a degree in archaeology. Their music has been licensed by many movie and television production studios, being included in numerous movie trailers and television shows. E.S. Posthumus released three albums overall in their career. 　　On July 22, 2010, it was officially announced that Franz had died about two months before. After giving notice of his brother's death, Helmut stated that while there still may be one or two unreleased songs (one of them being their single "Christmas Eve" released in November 2010), the group would no longer be active. In November 2011, it was officially announced that Helmut Vonlichten had formed a new band called Les Friction, and released a preview of his new work with a track called "Torture".
