Lana Del Rey’s “Once Upon A Dream” cover debuted with a new Maleficent trailer during the 2014 Grammy Awards.

Listen to “Once Upon A Dream” covered by Lana Del Rey in full below. You can download it for free via Google Play.

The song originates from Disney’s Sleeping Beauty released in 1959, but Lana is covering the song for the upcoming live-action movie Maleficent starring Angelina Jolie. The titular wicked villain made her first appearance in Sleeping Beauty, thus the decision to release a cover.

As expected, Lana’s version is much darker than the original performed by a colorful Disney princess. It’s simple with a slight radio effect over the vocals, making for a haunting performance that should please fans of Lana and intrigue Maleficent’s general audience.

The song will be available for purchase from Amazon soon. We’ll share a link once it’s officially released.

Check out the new trailer for Maleficent which carried the official debut of “Once Upon a Dream” below.

The synopsis for the movie reads, “A beautiful, pure-hearted young woman, Maleficent has an idyllic life growing up in a peaceable forest kingdom, until one day when an invading army threatens the harmony of the land. Maleficent rises to be the land’s fiercest protector, but she ultimately suffers a ruthless betrayal—an act that begins to turn her pure heart to stone. Bent on revenge, Maleficent faces an epic battle with the invading king’s successor and, as a result, places a curse upon his newborn infant Aurora. As the child grows, Maleficent realizes that Aurora holds the key to peace in the kingdom—and perhaps to Maleficent’s true happiness as well.”

The movie hits theaters May 30, 2014.
