You'll never hear "Once Upon a Dream" the same way again.

Lana Del Rey turns in a haunting cover version of the classic "Sleeping Beauty" tune for a new 90-second sneak peek at "Maleficent," which features our clearest look yet at Angelina Jolie in the title role along with an army of what appear to be fearsome tree-creatures conjured up the evil sorceress.

After checking out the full trailer above, you can download a free version of Del Rey's "Once Upon a Dream" over at Google Play.

"Maleficent" hits theaters on May 30.
