I think I'm the only person that's actually had a character as a member of a rock band, though if someone else has, I don't mean to exclude you.
Anyways. I have a fun roleplay idea. A rock band, maybe with some electronics (Like Muse), composed of (Maybe) villains. Kyte does let Erik out once and a while to have fun, and I suggest villains because I think that's the only people Kyte could get along with. Though it makes sense that they would all be their alter egos, so they perhaps could get along.
So here's what I'm thinking. First we can start with guitar, vocals, drums, and bass. Kyte can do possibly guitar, bass, and vocals, but I'll have him stick with guitars and vocals. The bassist could do some vocals, and hey, why not, maybe the drummer too, if he's good enough.
We could do with more sophisticated instruments like piano and stuff, but I think that's the basic concept of a rock band so far.
So now we have left
-Bassist
-Drummer
-Vocalist, if there's someone that's really good at them.
Anyone interested?
