Welcome!!!
I also understand the WHOLE mantra of being a musician and being overweight. it has always stopped me from performing live. I went to a contemporaty music college here in MN (for Music Business actually)and we were required to be in Ensembles (I was in Rock all 3 times

) I LOVE to perform but I was so self conscious up there!!! I don't know what I would have done if my mother told me people were making comments. I also have video of myself and I just cringe.
Again, I hate the stigma of the music business. I really do feel, though, that talent overcomes the physical. But it sucks when pop princesses sell records when they can barely carry a simple melody.
I doesn't matter though. I got your back girl, ROCK ON!!!!!! You are woman hear you ROAR!
