Digital art by Thomas Sutter.
There's a lot of underground independent artists who mix different sounds and music styles and don't have an specific or just one musical genre.
Dark electronic experimental music is a mixture of a lot of genres like: idm, noise, dark ambient, witch house, drone, glitch, downtempo & many others. Is something avant-garde but focused totally in dark thematics like ghosts, war, sadness, nightmares, occultism, religion, esoterism and others.
