Five nutcases. A whole bunch of instruments. The Finnish countryside. All that adds up to Steve 'N' Seagulls. This ragtag crew has been active since 2011, but they hit like a hammer in the summer of 2014, thanks to the popularity of their YouTube videos, which found them offering up S'N'S'ed versions of metal classics like Iron Maiden's "The Trooper" and AC/DC's "Thunderstruck".

Now you have the chance to see and hear Steve 'N' Seagulls for yourself, as the band has signed to Spinefarm.

One thing Steve 'N' Seagulls want you to know? They are not a joke act or a novelty.

"It took us about three years to get the sound we were aiming at," the band said of its origins and history. "We wanted to give a new life to songs we grew up with, not just do basic covers, and our agency provided the opportunity. Our agency needed a 'concept band' for theme events in restaurants. Now, we had been doing those kind of gigs before and knew the places to be probably half-empty. Still, it sounded like a fun project, so we took the job. After the first 20-gig tour, we wanted to keep on doing it and they kept on booking us gigs in nightclubs, pubs, cruise boats and such. After replacing our singer, we posted 'The Trooper' video on YouTube simply because we hadn't published anything with the new lineup. Then it just took off somehow. But we aren't complaining!"

Three years of touring in Finland brought the band some local attention. But it was those videos posted on YouTube that have already brought the band further acclaim than it ever imagined. "All of this started out as a much more small-scale operation, but hey, we'll take all we can get!," they said.

The band is working its first album at Studio Bad Mama, which is located at the outskirts of its hometown. The concept is a mixture of S'N'S's love for music and a celebration of childhood idols.

Despite the fun nature of the band, it's not a novelty act, with Steve 'N' Seagulls saying, "Even though we like to have fun with music we also truly take it seriously. That's why we feel that Spinefarm is just the label for us. We've been basically working on songs that we find interesting and what makes us feel good and laugh. It looks like accidentally other people found them interesting too. We're absolutely stunned to be working on our first album with Spinefarm. It's important to us that label is also all about music."
