Why do you want this? Why would you not want to be in a Christian band? Do you play and instrument or sing?
I played professionally in a rock/blues band for 7 years before God saved me. It was the worst time in my life. It is all about ego, and fame and glory.
The glory belongs to God alone. I will pray that God will open your eyes that you should not be worshiping this false god of stardom in a band. And that God will not answer your prayer to get pulled into this life of sin and degradation.
Sorry, you need to learn the truth about what you are asking. Once you have seen bands with lines of cocaine in the hotel room, and see them drinking 5ths of whiskey, you know you are on the very wrong path, Christian or not!
