This track is the perfect combination of ethereal vocals of Billie Eilish (still can't get over the fact that she is 13!?) and UK producer Astronomyy.
The original track is haunting and while adding some sound of his own Astronomyy managed to maintain this. What he does impeccably is bringing out the vocals and making them really the main component of the track. The tune is spacey and moody with a relaxed soft beat. Ambience at its best.
Check out the original here. These two tracks are really standalone masterpieces.
