First Listen: Caissie Levy Sings Elsa's New Song 'Dangerous To Dream' from FROZEN!

Frozen is currently in previews at the St. James Theatre, and already fans are getting more of a taste of the new songs added to the musical by composers Robert Lopez and Kristen Anderson-Lopez. Below, check out USA Today's first listen of one of Elsa's new songs, "Dangerous to Dream," performed by Caissie Levy.

Lopez tells USA Today: Lopez says. "We decided to write an 'I want' song for a character who's not allowed to want anything, and what she would want if she could but she knows she can't."

Frozen, a full-length stage work told in two acts, is the first and only incarnation of the tale that expands upon and deepens its indelible plot and themes through new songs and story material from the film's creators; in fact, this new stage production features more than twice as much music as the film. Like the Disney Theatrical Broadway musicals that have come before it, it is a full evening of theatre running over two hours.

Based on the 2013 film written by a trio of Oscar® winners, Frozen features music and lyrics by the creators of the film score Kristen Anderson-Lopez (Up Here, Winnie the Pooh, In Transit) and EGOT-winner Robert Lopez (Avenue Q, The Book of Mormon, Up Here) and a book by Jennifer Lee (Zootopia, Wreck-It Ralph), the film's screenwriter and director (with Chris Buck). Frozen won 2014 Oscars for Best Song ("Let It Go") and Best Animated Feature.

Frozen's director is Michael Grandage, a Tony Award® winner (Red) and director of three Olivier Award-winning Outstanding Musicals (Merrily We Roll Along, Grand Hotel and Guys and Dolls), and Rob Ashford, Tony Award winner (Thoroughly Modern Millie) and multiple Tony and Olivier Award nominee, is choreographer.

Frozen stars Broadway veterans Caissie Levy as Elsa and Patti Murin as Anna. The two women are joined by principal cast members Jelani Alladin (Kristoff), Greg Hildreth(Olaf), John Riddle (Hans), Robert Creighton (Weselton), Kevin Del Aguila(Oaken), Timothy Hughes(Pabbie), Andrew Pirozzi (Sven), Audrey Bennett (Young Anna), Mattea Conforti (Young Anna), Brooklyn Nelson (Young Elsa), Ayla Schwartz (Young Elsa), Alyssa Fox (Elsa Standby), Aisha Jackson (Anna Standby) and Adam Jepsen (Sven Alternate).
