Since you are not going there for the money, you get a month to figure out if you like it and if they like you enough to keep you on, the only risk you seem to run is the ticket. Since you have to eat/drink at home too, that is not a consideration.
Seems to me that -worst case scenario- you will spend the money for a ticket to go on a 1-month trip (vacation?!) where you even get to play at least one live gig.
Unless you are giving up a well-paid daytime job, I’d say it’s a bit of a no-brainer. Go and have yourself and adventure!
As for things not being what they seem, go with modest expectations and deal with reality in an optimistic way. It’s not adversity that makes the man, it’s the way he handles it (true for women too).
