Vulnicura is the eighth studio album by Icelandic artist Bjork, co-produced with Arca and The Haxan Cloak. Bjork said the album expresses her feelings before and after her breakup with American contemporary artist Matthew Barney and the healing process. Vulnicura was originally scheduled for release in March 2015. Following an internet leak, it was released digitally two months early. No singles were released to promote the album but a series of innovative music videos were created, culminating in the 360-degree virtual reality exhibit Bjork Digital. Vulnicura received widespread acclaim from critics, with many considering it one of her most honest and personal albums as well as her best output in a decade.
