Yeah, I do have some rough recordings of my band's material, but they're not really suitable I guess, since they're either all parts of different ideas and concepts or they don't have a specific 'uplifting message'. Also, if I were to do one of those, I would use my band's keyboard player, because they're also partly his songs
As for personal demos, I don't have a lot. I was thinking of making something new altogether if this idea goes through.
