The news report about the fire is reported by "Dirk Schneider", a reference to former Accept singer Udo Dirkschneider. He refers to the events as a "Symphony of Destruction" in reference to the Megadeth song of the same name, and when interviewing the dazed Dokken, she quotes "Monarch to the kingdom of the dead / Infamous butcher / Angel of death", the chorus of Slayer's "Angel of Death".
Lotvonen idolizes Megadeth guitarist Dave Mustaine, as seen with his Megadeth shirt, and playing Mustaine's iconic Jackson flying-V, but also in a more subtle note, the "SHUT UP" sticker on the guitar between the pickups; such a sticker can be seen on Mustaine's guitar on the Megadeth DVD "Rude Awakening".
When Oula walks away, Turo dismissively notes that "the drums were going to be backing tracks anyway"; it is an ongoing controversy and urban legend in the heavy metal scene that some bands may opt to play some or all of the drum tracks (especially high tempo kick drum tracks) from tape, unbeknownst to the audience.
Lotvonen spends most of the film longing after the guitar skills of Megadeth's Dave Mustaine; according to a Blabbermouth.net interview with filmmakers Jukka Vidgren and Juuso Laatio, they "totally wanted to have Dave Mustaine on the set", but ultimately it didn't work out.
Among the many memorabilia in the music shop, there is an urn labeled "Dio", supposedly containing Ronnie James Dio's ashes; a guitar on fire labeled "Jimmy's Guitar" in reference to Jimi Hendrix' infamous performance at the Monterey Pop Festival in 1967, where he set a guitar on fire on stage; and a tiny Stonehenge in reference to the iconic concert mishap in This Is Spinal Tap.
