She should start her own band--first, she should find someone who plays guitar or keyboard to work with(for a number of reasons, she should at least consider the possibility that this should be a woman) work up a set of the songs that she likes and does well, clean and polish, and then play in a few open mike situations, this way, musicians who like what she is doing will make themselves known, and she can get some exposure and work on her stage act--

If this sounds like work to her, tell her that she is going to have to do it anyway when she gets into a band--and this way, she'll have a lot more control--

Also, the truth about those bands is that they usually play a few paying gigs (the ones that the had lined up when they realized they needed a singer) then don't get any more, and end up slowly falling apart.

She probably won't pay any attention to this advice--my daughter, who is a good drummer(she even reads), and could work every night if she would just listen to what I have to say, never has--and her drum kit is just gathering dust while she works as a DJ--
