Emil is the lead singer and guitarist. I'd assume he'd be a decent singer in this AU... also I looked up pictures of Kurt Cobain a while ago and ugh he has an Emil-esque vibe I swear.
Lalli plays bass. Idk, he just seems like a bass guy? Not often in the spotlight, but without him the song falls apart. I just love to imagine Lalli playing bass.
Reynir would be the guitarist. He'd be playing the super high energy riffs while Emil plays the rythmic. Unlike Lalli, he'd have no problem with stealing the spotlight from Emil with his guitar skills.
Sigrun is destined for the drums. She hits the drums like she hits trolls.
And finally, Mikkel would play keyboard. I can see him as a tired music teacher who joined the band to get a bit of spice in his life... and secure some kind of income from it because he's
probably gonna get fired from his job sooner or later.
But wait! Where are Tuuri and Onni you may ask? Well, of course I haven't forgotten them!
Tuuri is the band's light and sound technician!! Since she's good with machines, it's the perfect role for her!
And Onni can only play old finnish songs on the kantele, so he's not really part of the band. He's reluctantly accepted the job of manager, though it's mostly to keep an eye on his cousin and on his sister while they gain in popularity. Also that icelandic guy looks really good playing the guitar... but he won't say that out loud.
