Four years after the release of her last album, Grimes on Friday shared a new song called "So Heavy I Fell Through the Earth."

The track is a preview of the singer's new album Miss Anthropocene, which she confirmed today is finally coming on Feb. 21 via 4AD. Fans had been eagerly waiting for an update, especially after Grimes confirmed last month the new record was "way done" and was simply dependent on some logistical matters being settled.

"So Heavy I Fell Through the Earth" arrived today with two versions, an "art mix" and an "algorithm mix," with the latter being shorter and more radio single-friendly, perhaps indicated by the use of "algorithm" in the name.

The new album will follow Grimes' album Art Angels, which was released in November 2015.
