Metalocalypse (2006)

Dethklok, a fictional death-metal band blending American and Scandinavian influences, exerts a powerful grip on its devoted fans, who obsessively follow the band's lyrics. Concerned about this influence, the government initiates secretive operations aimed at dismantling the group, even resorting to military-grade psychotropic drugs. Amidst the chaos, two band members grapple with alcoholism and the entire group faces deep-rooted self-esteem struggles, often resulting in erratic behavior, such as hurling hot coffee at concert-goers. Metalocalypse delivers a darkly comedic exploration of fame, fandom, and the absurdities of rock culture.
