Prepare for another healthy dose of eerie Swedish electronica: The Knife is back. The brother-sister duo of Karin Dreijer Andersson and Olof Dreijer hasn’t released a full album since 2006’s Silent Shout (unless you count their 2010 opera, Tomorrow, In A Year), but the pair announced today that Shaking The Habitual, their next record, will be released sometime early next year. Light Asylum’s Shannon Funchess is contributing to the effort.

To celebrate their return, the sibs have released a 43-second album teaser creepily titled, “We asked our friends and lovers to help us.” It features the two of them innocently enjoying an afternoon on the swings while clad in high heels, garish wigs, and leather onesies—which is presumably just how everyone in Scandinavia dresses. Like their music, it lives right on the edge of hauntingly beautiful and super, super creepy. [via Pitchfork]
