Yeah, I agree, but it somehow doesnt seem right to do a Fine arts major at college and go to a Business school for a master degree

Disagree. Business school is most valuable to those who are learning something different, not regurgitating and rehashing what they already know (which is habitually - though not categorically - inferior to workplace knowledge anyway). Admissions committees will evaluate whether someone with a Fine Arts background has the work experience, inclination and raw intellectual ability to handle b-school subject matter.
Math and economics simply reduces the burden of proof on your part. Doesn't make a hoot of a difference when it comes to banking recruitment; the b-school does 90% of the competency filter for the banks already, and they're interested in fit, your hunger and your stamina.
