Now he's taken this little project of his in the next direction, by asking people to create a visual to add to his music.
On his blog, Trent outlines the reasons for the album and what he would like to see happen:
This record began as an experiment with us using sound as a means to describe visuals. Early in the project we thought it would be interesting to see what the community could create / collaborate on as a reaction to the music we were making. We wanted to keep the canvas as blank as possible for you, hence the lack of descriptive song titles and the primarily textural artwork and packaging.
So here's the plan: we've teamed up with YouTube to host a "film festival" around Ghosts. The concept is for you to take whatever tracks you feel inspired by from Ghosts and create what you feel should accompany them visually. You will be able to see all of the submissions, and a team of us (including me) will be sorting through them and setting aside ones we feel are exceptional. Eventually (within a couple of months?) we will present a virtual "film festival" with me and some special guests presenting selections of your work.
Trent stresses that this isn't a contest and is instead more of a collaborative effort between the artist and the fans. He's not exactly sure what the end result would be, but the potential to have the visuals added to the textural musical sounds in some sort of large scale presentation is not outside the realm of possibility.
