There are two artists named Trist: 1) A Czech black metal musician. 2) A German ambient black metal musician.
1) Trist is a black/doom metal solo project from the Czech Republic, which began in 2003. Trist originally started playing raw black metal, a similar style to bands such as Korium or Holomráz, which formed around the same time. However, after a few demo recordings the style shifted towards his own extremely depressive and suicidal-esque brand of black metal which released his true feelings about life to the world.
