Re: Impossible to find driven musicians that's not already pro?
I don't know how old you are, but if you are over the age of about 25, prepare to be sadly disappointed. By that time most people have shifted their priorities to job, family, etc and the band becomes a hobby that is given only the amount of commitment that can be spared around "real life".
If you in your teen, early 20's you should have no problem finding other dreamers ready to take on the world with their music. You will rarely find those people on their own however. Most of them are already in a band and you will likely need to find a band that is really looking to take their music to the next level. You just need to keep looking and putting feelers out into the local music scene. If you are serious an opportunity will come, you just need to be ready to take advantage of it.
