Cover art for Zyklon B Zombie lyrics by Throbbing Gristle

a song about nazi death camp.Probably the 2nd after "dachau blues" by Captain Beefheart & the Magic Band. Here the singer is a jewish victim and a ss officer at different times of the song.Notes the line "and then my head split open !" has been taken from the Velvet Underground "I heard her call my name".

While we're talking about Velvet Underground references, I'd say that the "kiss the shiny leather" is derived from "kiss the boot of shiny, shiny leather", a line found in the Velvet Underground's "Venus In Furs". That's what I first thought of, anyway.
