Sigur Rós’ Jónsi and Swedish composer Carl Michael von Hausswolff are Dark Morph, and, today, the duo has announced a new album. Dark Morph is out May 10 via Krunk/The Vinyl Factory. Listen to the album track “BEKA YALO” below.

Jónsi and von Hausswolff’s collaboration began last summer aboard a research ship called Dardanella, and the album features their hydrophone and field recordings of humpback whales, bats, shrimp, and, naturally, dark morph herons. Von Hausswolff elaborated on their process in a statement:

While we were on the boat I started to take the recordings, manipulate them and mutate them into drones or other types of musical functions—so we could use the sounds as instruments for building compositions. We decided, “Let’s try not to have them sounding too much like real sounds, let’s turn them into something else.” When I had done some drones, some long tones out of a bird or something, I gave it to Jónsi and he started to peel off certain types of melodious things, and then play it to me. And then we started to just throw the ball back and forth.

Dark Morph will play a free show in Venice as part of the Biennale on May 10. Their music will also appear at the Venice Biennale as an audio gallery installation work at Ocean Space from May 7 to June 30.

Later this year, Jónsi and Alex Somers will embark on a Riceboy Sleeps anniversary tour. Find tickets here. (Pitchfork may earn a commission from purchases made through affiliate links on our site.)
