For some people, having to work with your significant other on a day-to-day basis would be something of a nightmare, but for the duo that make up atmospheric, dark electronic outfit OOFJ, it's a partnership that works perfectly. "It makes it easier... it means there is a shorter distance to send a creative idea to someone" declares South African Katherine Mills Rymer, whilst Danish partner Jenno Bjørnkjær agrees "the whole thing is just the same, like how we have an appointment and go to the studio at 3 O'Clock. It's more like just get up and it's part of the whole thing."

The LA-based pair are currently gearing up towards the release of their second album entitled Acute Feast, which builds upon their signature sound that was first exhibited through their debut Disco To Die To. Made up of grand, sweeping string arrangements, eerily beautiful vocals and dark synths, their sound is cinematic with a touch of danger to it and is notoriously hard to define. Even the duo have differing view on how they would describe it: Bjørnkjær sees it more as a dark symphonic experiment, whilst Rymer ponders "our sound is like... underwater. I was saying to someone the other day, it's like those squid that are right at the bottom of the ocean, and they are huge and giant and see-through and if you shine a light on them, they have crazy lights on them. They are kind of like them. Like the sound of water, that's kind of quite big."

Since meeting in New York whilst Rymer was training to be an actress and Bjørnkjær was training as a Jazz musician, the couple began working together on music, almost by accident. "Ut made sense to make it as a band," says Bjørnkjær. When speaking to the pair, you get the sense that they are each very different people, but meet somewhere in the middle when it comes to making music, and it is that pulling together of different influences - ranging from Russian Noir films and classical music to a joint fascination with dark themes and relationships - which make the pair's music so enchanting to listen to. We caught up with them to talk more about what to expect from the new album.

Katherine: I've been trying to describe that to my friends. And I mean, I don't even know what this means, but it's kind of like, a boozy lunch, but like in some in Tuscany at night. I know that sounds very kitsch, but I don't mean it to sound like that... Jen has his hands over his eyes right now. It's kind of like...

An alcohol-fuelled summer evening would you say, maybe?

Katherine: Exactly! Exactly that!

When you began writing the album, did you have a particular vision of how you wanted it to come across? Or was it more organic than that?

Jenno: It was totally organic. We basically starting working on it almost immediately after the first album came out, because we had an idea about releasing a year after on the same date... Which did not happen... But, we just started working on it, and making all these tracks.

Katherine: Yeah, and I think this time it has been a little bit more obscure. There's no conceptual work. For us, we just have to make a lot of things, then sit with these things for a little while, and then. It's really hard when you make things, because you'll like something for a week, or even three months, and you'll hear it again and just go "that is the worst thing I've ever heard! I just want to die, that's all." But yeah, the sound comes about by itself.

Was it the same process for the first album, or was this a different way? Or is this the way you've always worked?

Jenno: The first album was made in a very different way, because we did not make music together before we made that album, so it was kind of done a lot on the road. Not touring, but travelling a lot. A lot of things happened. And then we couldn't get back into the United States, because of VISA issues. So we did some road tripping in Europe, and went from there. We didn't even have a plan.

Katherine: It was never really planned as an album, nor was it that there would be any kind of group, or sound, or anything. It was just making things. It sounds very flakey, but really.

It was quite natural?

Katherine: Yeah, I suppose. I mean the whole thing just happened. And then we were like ok, and we had 11 songs and 10 went on. So we didn't have lots to choose from, we just had that, and that's what went on the album. But this one...

J: Well basically, we had just started making music together and it turned out to work really well. And then it became a thing to do. It made sense to make it as a band.

Is there a story behind the title of the album? Why is it called Acute Feast?

Katherine: The last album, Disco to Die To, came about because I was literally describing to a friend what I was doing, and just said "you know, it's like, death, disco to die to." This one... Acute I like as a word because it's normally related to something bad, like 'you're acutely ill', so no one really uses it. At first, everyone thought I was saying ' a cute feast' and I was like no... There was a language barrier there.

Jenno: It has a slightly different meaning when you translate it into a Danish language. I understand it now.

Katherine: The decadence of it, it's like exhaustive pleasure.

It's very severe as well.

Katherine: Exactly! It's always like... too much of anything is gluttony... but also gluttony has a plump, nice thing about it. Something you want. I know, it's kind of obscure. But, that's how I feel about it.

You've said you're very controlling over your artistic aesthetic and still make your own music videos, why is that creative control so important to you?

Jenno: I really feel like it is exactly the same as making music. It's like we are making the music that we like to make, and it's important. And then making the video is basically the same thing. We have ideas of how to make it, and what would be awesome to look at, and just kind of go with that. In the beginning it was something that we had to do. That's what you do when you make music, you make videos. And then we started getting into it a bit more. And understanding what it is, and figuring out what those ideas are. We worked with someone else in the beginning, and that was great as well, but it was just a little bit off what we actually wanted it to be. And it's very fun to do.

So what was the story of the latest video 'I Forgive You'?

Katherine: We are fascinated by couples and the weird stuff that is inside that. so you unpack that. The idea that you can live with stuff- and this isn't the case with us - but the idea that these two people are not really intimate - hence the masks - and they can't show their true face. And looking at those little things that people do in a relationship that - like cutting toe nails - and you can imagine her like "please no! I'm going to freak out!" They never really confront what they have.

Jenno: It's like a relationship and you can't be who you are.

A lot of your music is heavily influenced by music from the past, particularly classical Russian orchestral music. I was wondering whether you ever feel as though you were born in the wrong century?

Katherine: Sometimes... I think that we bond over a lot of classicism and we are very into Russian films, but I'm very glad that I live in the age of the internet. But it also puts me in a very bad mood. But I don't want to live in 1910. Or the '60s. But the '60s in LA would have been the bomb.

Jenno: I'd like the 1940s in LA. As a jazz player, in the '60s would have been awesome, and it was so fresh and modern. And that would have been exciting.

Acute Feast is due for release through Ring The Alarm/Fake Diamond Records on 21 April 2015
