Watch: 'On The Rocks' first trailer + Phoenix share soundtrack song 'Identical'.

Phoenix have shared a brand new song, 'Identical', lifted from the upcoming film 'On The Rocks', which frontman Thomas Mars' wife Sofia Coppola has directed.

The first trailer for the film, which stars Bill Murray and Rashida Jones as father and daughter, has also dropped ahead of its release this October.

The song will feature in the end credits for the film, and the band have also written the score and assembled the soundtrack. In an interview with Zane Lowe on Apple Music, Mars shared the following about the new song and their next album: "This is the time we're putting one song and it's our original song. So I think, yeah, and also I think this song will be on the album somehow. Even though the album now feels like it's all over the place, we know that in the last few weeks it comes together, and it doesn't look like anything now, but it will come together on it. It all makes sense.

It's a good thing that it's all over the place. As a musician, it's the most exciting moment because everything's all over the place. There's no coherence and it's a little bit like our first record, maybe; United, which had songs that would explore heavy metal and then country music. And then this is the same sort of weird Frankenstein of an album."
