"Metal Lords" is a 2022 American film. It follows two high school best friends and metal music lovers, Hunter and Kevin, who set out to start a metal band, against societal norms.

Guitarist Hunter Sylvester jams with his best friend Kevin Schlieb, who plays snare drum in the school's marching band. Hunter spends $13000 (on his dad's credit card) on equipment including a full drum set for Kevin. They now need a bass player to complete their band "Skullfucker" and enter the Battle of the Bands at their high school. Kevin meets Emily a skilled cello player. Romance ensues, which prompts Kevin to give her a copy of a playlist of metal songs that Hunter assigned him as "homework". She learns all the bass parts on cello but Hunter thinks a girl in the band is not "metal". This causes Emily & Kevin to break up and Kevin to quit the band. Kevin starts playing with a rival high school band and at a drunken party gets into a hot tub with a girl.

While they are kissing, Kevin's conscience materializes in the form of heavy-metal musicians Scott Ian, (rhythm guitarist and co-founder of the band Anthrax), Tom Morello, (guitarist and singer best known for his tenure with Rage Against the Machine), Kirk Hammett (lead guitarist in Metallica) and Rob Halford (lead singer for Judas Priest).

Halford makes Kevin realize that he indeed loves Emily. Kevin also realizes that he needs Hunter back, only to discover that Hunter was sent to rehab by his father, as a punishment.
