Ellie Goulding's covered everyone from fun.'s "Some Nights" to the Weeknd's ethereal "High for This" to Rihanna's "Only Girl (In the World)." Now, add psychedelic indie rockers Alt-J to the mix.

For her rendition of their single "Tessellate," the electronica-rock song is transformed into a stark, electro-pop joint focused on Goulding's soft vocals. The singer incorporates layered harmonies, slinky synths and a fresh saxophone section, leaving only the vaguest hint of the original.

Take a listen to the Alt-J's original here to compare. Who do you prefer to "tessellate" with: Goulding or Alt-J?
