* That faceless gigantic Galactus on the cover of their debut album ''"Monster Movie"''.
** Their epic improvisation [[https://www.youtube.com/watch?v=QxX5ZORy95w "Yoo Doo Right"]] is very unsettling, with wailing, croaky, almost proto-screamo vocals that sound like a man weeping about his girlfriend over the top of tribal drums and strings, pounding menacingly and apocalyptically. Knowing that Malcolm Mooney, the vocalist heard wailing the vocals, suffered a mental breakdown shortly thereafter doesn't help much.
* Most of the material on ''Tago Mago" qualifies for this trope.
** "Mushroom": a claustrophobic track where Damo Suzuki babbles about a ''"mushroom head"'' and ''"he was born and he was dead.''" It's heavily implied he's singing about a mushroom cloud from an atomic bomb explosion and all the terror he witnessed then. The song concludes with the sound of a atomic bomb explosion, literally blasting everyone and everything out of existence.
*** The immediate next track, "Oh Yeah" is sung completely backwards and sounds as if [[AfterTheEnd nuclear dawn]] has set in.
** "Halleluhwah": a dark, hypnotic percussive track. Though, for some people, it is also a very sexy tune.
** "Aumgn", a haunting track driven by Schmidt's weird vocal sounds.
** "Peking O": at a certain point the music sounds neurotic and Suzuki starts yelling freakish sounding gibberish, much like someone GoMadFromTheRevelation.
