Well, Hell. Now I’ve got to go back and catch “Heavy Trip,” the Finnish metal band comedy from 2018, the movie that inspired “Heavier Trip.”

“Heavy Trip” is on Tubi. Do your homework before catching the sequel in cinemas! It’s free!

The sequel is fitfully amusing and watchable. But you can sense the greater silliness that inspired it in this “Blues Brothers go Metal” road odyssey.

The band’s name is Impaled Rektum, which is pronounced “Im-PALL-ed” Rectum in Finno-English.

“The Most Brutal Metal Band in the World” didn’t make it big in Norway after their “Heavy Trip” from Finland to the land of herring eating A-ha fans. But they caused so much chaos and destruction that they landed in prison.

Ah, but this is a Norwegian prison, famed for “the best seafood buffet in Scandinavia,” for its spa and its pussycat of a warden (Mats Eldøen), whose goal is “a prison people will WANT to come to.”

But hardcase head guard Dokken (Helén Vikstvedt) won’t let lead singer Turo (Johannes Holopainen), Dave-Mustaine-worshipping guitarist Lotvonen (Samuli Jaskio), easily-triggered drummer Oula (Chike Ohanwe) and metal purist/KISS cosplaying bassist Xytrax (Max Ovaska) play their “symphonic apocalyptic reindeer-grinding, Christ-abusing, extreme war pagan Fennoscandic metal” behind bars.

When a promoter by the Satanic name of “Fisto” (Anatole Taubman) dangles a spot at Europe’s biggest metal festival, Wacken, they’re tempted to escape. When Lotvonen’s family is about to lose their reindeer slaughterhouse, that cinches it. They need the money.

Impaled Rektum make a break and do what needs to be done to get to Vilnius, then Rostock — “the smell of fish and PILSNER” — and eventually Wacken, with Mephistophelian Fisto changing the nature of their “deal” every stop along the way.

There’s nothing supernatural about the “evil” promoter, which is kind of the joke. They’re all just…evil. Make your deal with the Devil and get on with it.

They’re pursued by the fanatic prison guard for stealing her beloved camo-green ’96 Jeep Cherokee “Armando.” They stow away on the tour bus of metalheads Blood Meter and their artificially-deep-voiced singer Rob (David Brendin), a band that “was” the biggest thing in metal. For a minute.

Impaled Rektum stumbles into and torches a metal memorabilia shop and museum in Rostock where one can see Lou Reed’s liver, Dio’s ashes and Jimi’s eternally-burning Stratocaster.

Mr. “That’s not metal enough” bassist Xytrax, who changed his name from “Pasi” in the first film, will hear a J-pop girl group’s take on metal music and be smitten…and compromised.

And lead singer Turo will be tempted by Fisto to leave the band and set up as a growl-shouting solo act.

The jokes start in prison — a guard who begs them (in English, mostly, with some subtitled Finnish) as they escape, “Don’t forget to RATE us,” the endless Metallica references, the chest tattoo quoting what Dave Mustaine thinks of your opinion about his guitar solos, the “metal” makeover they get when they sign on the dotted line.

Some gags work, some don’t. The band is “just one concert from being the biggest thing in music,” and the movie about them is about a dozen jokes from being as funny as the supposedly-serious documentary “The Story of Anvil.”

The first “Trip” film is daffier, with sillier world building — long haired metalheads in rural redneck reindeer herding country. This time there’s no potential love interest, no finding  “our sound” from the noise of a reindeer grinder (a laundromat dryer serves that purpose here), no dead end jobs —  just a Norske prison to flee.

Yeah, I’m cranking up “Heavy Trip” on Tubi to see what possessed them to take another stab at this material. Because if there’s a music genre more thunderously tone-deaf to how funny their mania, mores and rituals are, I’ve never heard of it.

Fennoscandic, apocalpytic reindeer-grinding? Totally there.
