From the press materials:
Following on from his Flags Mixtape, which appeared at the start of 2014, Brolin releases a brand new track, Swim Deep. The track is the first to emerge from sessions with producer Raffertie, as the two finish work on Brolin’s debut album, expected early 2015. The video for Swim Deep, directed and produced by Phoebe Arnstein, features three couples as they allow cameras to capture their tender post-sleep moments. Each graceful shot captures the lyrical intimacy of the song, to gorgeous, enveloping effect
Lovely and simple.
