I began working with Immogen Dillon in 3rd year film on Procession - a film about a funeral/wake, and friends.
A good suggestion I had was for her to send me and the other collaborators a playlist of inspiration/music ideas. This really helped me with the direction of my piece. I made the final song of the film, to be played in the last scene at the beach and into the credits. The main inspiration for this piece was Perfect Day by Lou Reed, starting off gentle and building to a crescendo, expressing melancholic tone, bittersweet feeling of letting go. On the playlist there was also some Beach House which made me want to use drum machines, synth, reverby vocals etc.
Another thing that really helped was that I made 4 demos of songs that could work, and sent them to Immogen, and she decided on one that fit the vibe. This made sure I was headed in the right direction before I spent ages on recording.
I finished the main song for the outro, and sent off the mix, and Immogen asked to if she could use the other demos for other gaps in the film. So I ended up with Demo 1, Demo 2 and Procession as the 3 songs in the film. Also I sent them a version of the song without singing so they could also use that in other parts of the film.
