The song "Demon Lung" by Electric Wizard tells a dark and twisted tale of a protagonist burdened by a 12-ton demon on their back and haunted by a Martian witch. The demon constantly whispers negative and disturbing thoughts into the protagonist's mind, while the witch, who has experienced things that are beyond the imagination of her mother, pleads with the protagonist to repeat their destructive actions. The lyrics suggest that the protagonist has engaged in unwholesome activities in the past, potentially involving violence or addiction, and the demon and witch are urging them to continue down that destructive path. The repetition of "Yeah! Yeah! Yeah!" adds an element of urgency and repetition, highlighting the relentless persuasion from these dark forces. When the protagonist asks someone to "load me a demon lung," they are essentially seeking an escape or a way to numb themselves from the pain caused by these haunting influences. This line can be interpreted as a plea for relief or assistance from the darkness that is suffocating them. Overall, "Demon Lung" portrays a struggle with inner demons and external influences that push the protagonist toward destructive behavior. The song's lyrics effectively create a dark, eerie atmosphere, reflecting the band's signature doom metal sound.
