It also tells you to have a beer, tube the river, and then join a band.

I don't know Austin, why is it?

Actually, you're picking up the last bit wrong..."and join a band" is actually the way the last bit of the message goes. But close enough.

In personals ads in Austin, "musician" is code for "unemployed", because everybody is a musician. You only mention it if you don't have anything better to say about your career.
