Zola Jesus: as well as making her own music she is part of Former Ghosts and has supported Fever Ray, therefore you might assume she makes some really very good music. An assumption in which you would be correct. Her latest release, an EP by the name of Stridulum combines her astonishing vocal range and power, with dark lyrics (for example on the single, Night "because in the end of the night when all we have is gone ").
The EP artwork is a particularly striking image, Zola Jesus herself covered in a dark viscous substance (which I seem to remember reading somewhere is actually chocolate) and this reflects her music brilliantly. Surprising at first, difficult to get out of your head, but also quite sinister and unusual.
