I've been trying to get into the music biz and I know its hard but I want to go into it knowing what I want to be. SO I need a stage name. I want soemthing cool and short like Lady Gaga so people can call me something short. My name is Olivia Bannerman if that helps. I've Seen Eden Savage and stuff like that but I want soemthing short and sweet..... or somthing long and cool! I don't know! I just need some input. Please help me! I would really enjoy it if I could see what you had to say. And i know this may be a bit much to ask but could you put a little thought into it? thank you so much!
