Goodnightm4rk

goodnightm4rk is the experimental alter-ego of Mark Anthon Kiessling, who is most known by his main stage name, JUMEX.

Under this stage name, Mark has released only a handful of singles, the first being "DNTTALKTOME." These singles feature more low quality vocals compared to what has been heard from JUMEX, as seen in "Lost in Space."

On March 13, 2020, Mark would release his debut demo EP as goodnightm4rk, titled NIGHTMARES.
