Sometimes Frühstück band is in Haunted Memories. Like in the official trailer. The song there is from Frühstück, the song is called: Pig. Also if you saw a wallpaper of Haunted Memories it said, above the Haunted Memories letters. "Sometimes darkness leads to light". That song is called: Follow. So there is a song that is related to slender man. Called: Quiet. Not the album quiet but the song.
so you can enjoy their songs on Spotify!
also their are my no.1 favorite band!

I also found them through Haunted Memories, I recommend "Twister of Life", it wasn't used in any HM trailers but it is really good!
