I'm having a music crisis. I was thinking last night about how my band hasn't done anything in ages and I'm too busy with work and other parts of my life to do a side-project with anybody else, so I decided that I'm gonna concentrate on putting together my own music and maybe, if I ever get round to it, getting some people together to perform it. However, I've hit a brick wall in terms of creativity. I've been sat here, pretty much since I woke up today, with cubase open and my bass in hand but my brain will not imagine anything good. I don't know what's happened to make all of my creativity abandon me so suddenly and now I'm freaking out because what if it never comes back?! 
i hope your creativity finds you soon.
