“Lying next to you, we could be on the moon,” Natasha Khan purrs as Bat for Lashes on “Kids in the Dark,” from her 2019 album, Lost Girls. The record is a little more diverse than The Bride, the English singer’s powerfully moody, cathartically melancholic 2016 record of love and tragedy. Lost Girls ranges from the funereal, engrossing incantation “The Hunger” to more bubbly dance-pop tracks like “So Good” and “Feel for You.” At times, the soft, shiny arrangements veer too much toward New Age insubstantiality and generic pop, which makes the relatively stripped-down album-closer, “Mountains,” all the more vulnerably affecting. Khan’s earnest if cloying vocals can’t rescue a cover of Don Henley’s banal “The Boys of Summer,” but Bat for Lashes’ new live EP of the same name is buoyed by intimate versions of “Daniel” and “Desert Man.”
