Suggestions for asking out the singer.

[Aspire]

I want to ask out this drop dead gorgeous musician next time I go to a gig of hers. For reference, I saw her just over a week ago and that was the first time I saw her in 7 years. Obviously, if I am given a negative response I should not resume to go see her (you know, have to be willing to walk away) and I am prepared for that as I see her worth the risk.
That said, and suggestions on the approach? Date suggestions considering she is a musician? Should I just ask for the number? Any thoughts?

So you want to be a middle aged male groupie?

The same way you would any other woman.

Strike up a conversation after she is done performing and the crowd has cleared out. Should be really easy to ask her about music, how she got started, etc.
