AdWeek:

Lovingly, meticulously crafted through a combination of detailed miniatures and digital animation, Apple’s “Share Your Gifts” is the tech brand’s most ambitious holiday ad to date—and one that only gets more impressive with each subsequent viewing.

Among the many visual Easter eggs hidden throughout the spot, there’s also an audio surprise you wouldn’t be able to guess just from listening: Like the fictional star of the ad, the musician behind the commercial’s song is a young artist who began by writing pieces on her Mac.

Billie Eilish, a 16-year-old American singer, recorded the track “Come Out in Play” specifically for the ad. Eilish, who began writing songs at 11 and was signed by Interscope at 14, recorded the spot’s song in her parent’s home with the help of her producing partner and sibling, Finneas O’Connell.

We posted the video yesterday but this article has some great detail about its creation along with a “making of” video and links to other Apple holiday spots from the past.
