Oh, how tongues wagged when Bjork stated her plans to release an album that (mainly) featured the human voice in its many contorted forms. Having released a pure masterpiece, Ms. Godmundsdottir had the last laugh. Medulla left people lost for words - in the best possible way - and this single honours Bjork’s tradition of marrying complexity with atmospheric esoterica. As one of the album’s more accessible tracks, ‘Who Is It’ is the perfect gateway into Bjork’s wonderful, if a little warped, world.
