The four-track EP was written during the production of Flume's studio album, Skin, and was released digitally on 17 February 2017, by Future Classic as a companion to the album.

Upon release, Flume said: "I'm really happy with how the Companion EP 2 has come out.

There's so many tracks I've been wanting to get off my chest for so long now and I think it's kinda the end of the Skin kinda campaign and it's a nice way to end it because it's instrumental stuff, there's some vocal collabs...

Skin Companion EP 2 received mixed to positive reviews by critics.
