And she spectacularly lived up to her oddball reputation at the Roskilde Festival in Denmark yesterday.
The Icelandic visionary turned up for her headline gig in a frock adorned with strange robotic-looking snakes.
She teamed the slithery number with a hairdo that would scare off most living reptiles, opting for a multi-coloured barnet.
It’s the kind of hairdo that can only usually be achieved by placing one’s finger into a plug socket.
But it was her ‘dress’ that truly caught attention, evoking memories of the wacky swan outfit that she wore to the Oscars in 2001.
Björk went down a storm with fans last night, despite ignoring all of her best known songs.
She barely opened her mouth to address the crowd between tunes and focused heavily on material from her latest album Biophilia.
One reviewer wrote : “I have mixed feelings about last night’s show. It was strangely paradoxical to be bored in the presence of greatness, and there were moments where I wished she would drop the Biophilia act and went all out like she did 16 years ago.
“But as a Björk fan, I think you have to be willing to let her take the lead and fulfil her own vision.
“She is a headliner of the highest calibre and a true artist. Her performance was a statement to her ability to reinvent herself and at the end of the day, she did was she does best – she was herself.
“And the audience got to journey through her wonderfully bizarre world.”
