Heh! My friend and I are currently in process of a music video that I'm releasing 3 days before the comic's launch (Sept 13th) as a countdown type thing. xD
I make music and my friend is a motion media artist, so we're both very excited for it. (I am paying her for her time, even though she is refusing monetary compensation because I'm a friend. So, I'm paying her in food! LOL)
It's just a 1 minute long theme song for the story, and is going to be an abstract music video (shapes and colors and crazy motion). At first, I wanted to just post an audio file of the theme song, but I thought about any potential readers who may be deaf (I have a few friends myself who are hearing impaired). So what better way to convey sound than to have some music video for them to at least look at? That's how it turned into a video.
I say, if you can do it, then go for it! I think it's a great way to reach out to more people and get others invested. But it does take time and energy to put together.
