A client needed a video to illustrate an upcoming event titled 'Call of the Wild'. We were reluctant to use copyrighted music, and wanted a soundtrack to highlight the nature of the event, so I decided to make a soundtrack to accompany the video. The benefit being, I could more tightly edit the piece to the music, and was able to create a length and feeling ideal for the effect we wanted to achieve.
In many pieces, I have been able to add custom sound effects to an opening title sequence or branding, for example. In larger projects, entire sequences were re-created because the original audio was not good enough, for example, in my short film
Bon-Zo: Chapter 2. The entire film's audio was recreated in post, including a complex boxing sequence, full of effects.
Finally, there is music creation for the sake of pure artistic expression, as in the following examples. In these songs, I have taken dream narratives recorded by a couple of my friends, and edited them to a new song creation. The second song was two different dreams by two friends, recorded in very different circumstances, but I decided to edit them together as if it's a conversation between two people. The narrative makes no sense upon further examination, but sounds like a cohesive whole when listened to casually.
