London’s Helena Costas sings of King Arthur and jousting knights, giant flying trolls, and a magical bull that avenges the injustices of man. Not interested? Well, Danger Mouse produces and cowrites the creepy tunes, while Quentin Tarantinoapproved soundtrack composer Daniele Luppi arranges austere strings, and Neutral Milk Hotel associate Scott Spillane contributes elegiac horns. Sounds better, doesn’t it? Costas coos anachronistically whimsical and hallucinatory lyrics as if she were the ghost of an ill-fated fairy-tale heroine, and the haunted results suggest the greatest psych-folk obscurity you’ll never afford on eBay.
