Their disturbing cover of "I Can't Get No Satisfaction", which mentions that the narrator stabs and kicks whenever he can't get popcorn at the movies, among other things.
Large chunks of The Commercial Album, including "Die In Terror," "Margaret Freeman," and "My Work Is So Behind."
"Die In Terror" has a creepy title to start with. But the sound of those footsteps during the intro... (shudder)
"The Act Of Being Polite" is also frightening. Especially when it turns out the protagonist killed a women because he "was just exhausted from the act of being polite."
Third Reich And Roll album contained forty disturbing cover versions of top forty songs from the 1960s. Among many bizarre warpings, the bitter-breakup garage-pop standard "Hey Little Girl" becomes a genuinely chilling piece with a mocking, serial killer-like vocal and grimly march-like music which features plenty of ominous buzzing, droning and rumbling noises in the background (powertools? Brrr...). It must have been a very bitter breakup, indeed.
At a certain point the music just stops and you suddenly hear a car crashing, guns shooting, a baby crying and an air-raid siren.
The cover of "Yummy Yummy Yummy (I Have Love In My Tummy)" also sounds disturbing during the second half.
