OLOF Arnalds has a playfully experimental and profoundly sensual new album to promote at Fibbers in York on Saturday night.

Palme represents the Icelandic singer-songwriter's most collaborative studio collection so far, moving her forward from the acoustic approach that defined her first three records, 2007's Við og Við, 2009's Innundir Skinni and 2013's Sudden Elevation.

She is backed on the record by trusted friends and collaborators, Gunnar Örn Tynes, founder of electro-folk collective, múm, and long-term musical foil Skúli Sverrisson, who has worked with Laurie Anderson, Ryuichi Sakamoto and Blonde Redhead.

Lead single Patience, written by Sverrisson, boasts an almost Polynesian vocal sway while Defining Genders is marked by bossa nova and swelling strings. Elsewhere, subtle electronics guide Hypnose’s gentle propulsion and Half Steady’s strange, robotic cacophony. Some songs, such as Turtledove, are new; others are old friends, Half Steady having been written by Ólöf while still in her teens.

In many cases the shape of the songs – even chord structures and melodies – were transformed entirely during the six months of Palme’s gestation.

“It took a lot of trust to let my collaborators so far into my musical expression and at times I found it a bit frightening”, says Ólöf.

“But now when I listen to the record, I feel that the music is no less on my terms than in my previous work. It feels more like out of nowhere, the record I've always dreamed of making has become a reality.

"Skúli, Gunni and I all contributed from our different experience, aesthetic and skills in a very open, straightforward dialogue. What worked best musically always ended up in the songs; the darlings were killed with no regrets.”

Palme was released this week on One Little Indian; tickets for Saturday will be available on the door.
