It seems totally logical—if not actually inevitable—that Tori Amos would eventually write a musical. Over the last two decades, the singer and composer has created work that exists in its own rarefied universe. Her music is often character-driven, populated by winding narratives in which Amos herself serves as both muse and guide. It is these talents that Amos brings to her musical The Light Princess, which made its debut at London's National Theatre in 2013 to great acclaim. Based on the 19th-century fairy tale by George Macdonald, the musical tells the story of a prince and a princess, who each lost their mother at a young age. The young prince becomes so forlorn that he is unable to ever smile, while in another kingdom a young princess becomes so light with her own grief that she floats into the air. Balancing the whimsy of a floating heroine with heavier themes regarding grief and rebellion, The Light Princess feels both remarkably contemporary and incredibly prescient. Though it remains to be seen when a full-scale production of the musical will arrive stateside (Amos hints that plans are afoot), the original cast recording was released earlier last month—a beautifully-packaged disc that includes two songs from the musical performed by Amos herself.
