When an artist calls the people of their hometown their family, it's usually a metaphor. In the case of Björk Guðmundsdóttir it’s actually true. Reykjavik has a population of only 200,000 and everyone is somehow related. But she's more than just the capital's favourite daughter: to the outside world the diminutive singer has become as emblematic of Iceland as its volcanoes and midnight sun. In turn, the uniqueness of the country helps fuel Björk’s individualism.

An album that encompasses pan-global collaborations, iPad/Phone apps, internet jiggery-pokery, art installations, live multimedia shows and even a tuning system, with the “Ultimate Edition” of the album coming complete with a set of tuning forks to demonstrate this. As ever, Björk Guðmundsdóttir is showing no shortage of ambition. But is it any good?

Björk’s Biophilia is a five-headed organism: the album (itself issued in five different editions), the app, the documentary, the live show and the website. Here in Harpa, Reykjavík’s spanking-new concert hall, Björk is in her home town, delivering the live show, performing the music. She’s playing residencies rather than touring. Instruments have been specially made. A giant spark arcs between two Tesla coils. Four massive pendulums swing.
