Imagine someone's told you about this great 26-year-old female Swedish singer. You're probably thinking of pop music, something electronic, following the trend of excellent uplifting music we get from Sweden, and its neighbouring Scandinavian countries.

Well, that isn't quite Anna von Hausswollf. Not even close, really, apart from the defining characteristics of age, gender, and location. This isn't summer music, that's for sure. Are church organs even capable of making summery music?

Of course, if you'd looked at the tracklisting, you probably could've taken a guess at the sound of Hausswollf's latest album, Ceremony. Epitaphs, funerals and deathbeds all feature in songs' titles. But despite the heaviness of the matter, it's a surprisingly easy listen. The dirge of opener 'Epitaph of Theodor' gives way to an expansive, swooning sound; it gives way to 8-minute epic 'Deathbed', one of the best tracks on the record.

A slow starter, it's dark and brooding, but you never actually feel the length of it too much, possibly because the song feels broken up into two halves, split by the moment von Hausswollf's powerful vocals come in. Considering much of the album is played out on an organ, her words don't get lost amongst the sounds - an achievement in itself. Instead, the two powerhouses work together harmoniously.

'Red Sun', one of the shorter tracks on Ceremony, is beautiful in a different way. It's more delicate, but still dramatic in its own way. Without meaning to demean it, you could probably see it closing an episode of Game of Thrones. You know, after they kill everyone in the last five minutes.

The only problem with Ceremony is that, with one core instrument, some of the tracks do have a tendency to blur into one another. That's rectified in tracks like 'Liturgy of Light', which twinkles with different sounds, and is gorgeously melodic.

It's not an album you hear every day. It's deep and powerful, and your everyday singer-songwriter couldn't construct such a record. The uplifting 'Sun Rise' closes Ceremony, and as it ends, you feel yourself almost blinking in the sunlight, as you emerge from having witnessed a real aural ceremony.
