In March 2018, a three-remix package was released with remixes from Aoki, Alan Walker and Garmiani.

[3] Musically, "All Night" is an EDM song, with lyrics about finding someone special.

[4][5] Billboard's Kate Bain noted "All Night" sees Aoki's returning to "bright-light, electro-house grooves" after the hip-hop influenced production on his Kolony LP.

[6] Introduced by their managers, Aoki played different tracks to Jauregui and they exchanged ideas.

[7] Jauregui said they had agreed on an unfinished track with a "delicate side" which she then reworked, rewriting lyrics, changing melodies, adding a bridge, and creating the harmonies.
