Iconic band Metallica joins the #MetalocalypseNow campaign to bring the Part-American, part-Scandinavian death-metal band Dethklok on screen again by shifting the final season to Hulu. The heavy metal group even sent a note and a handful of guitar picks to the online company to hear their cries.

The legendary musicians sent the package in response to the animated television series creator Brendan Small's call to release the final season after the show's former network Adult Swim didn't renew their contract for its final run. According to Ultimate-Guitar, Metallica sent the note to the streaming media's Head of Content.

"Everyone here at Metallica HQ would really appreciate if you can finish Metalocalypse so we can watch it on your lovely service. Thank you for your attention in this matter," they wrote the letter. "Oh, and here are some guitar picks."

 Oh HULU! Incoming! #metalocalypsenow #metallica

The campaign started at Brendan's AMA session with UG. While he was answered all questions of his supporters, he asked his fans to urge Hulu to host his creation's final season.

Since then, his request went viral as big names such Metallica even hear his request. "Here's all that I know: I have a final story I really like, and I think since Hulu currently has a license for the streaming rights I believe that would be a good place for the final story," Brendan said.

"If they were to partner with Adult Swim, then maybe we'd have a place for the shows that still have a strong audience that the network can no longer afford," he further explained. "Get on Twitter or Facebook and tell Hulu how much you love Metalocalypse and who knows what'll happen?" he added.

Meanwhile, the news was followed James Hetfield's hint that Metallica are working on a new album. The 52-year-old front man gave a clue about their upcoming LP while his talking about his guitars, Music Feeds reported.

"I tell ya, we're recording right now, and there's the number one guitar, there's the number two guitar, there's the number three," he said. "And here's the third-track guitars that just sound different. They all sound different," he added.

This was also accompanied by Kirk Hammett's confirmation earlier this year that they were polishing everything in a studio. "We have a lot of good songs," the 52-year-old lead guitarist told Billboard. "We have well over a dozen songs and we still have well over two or three hundred riffs, too, so it's hard to say at what point we actually are in in the project."
