I think it's a waste of time. You're setting yourself up for a world of hurt with this scenario, if you or your parents are taking out any student loans. If they're not, if they've saved wisely and can write a check, you're still better off just going to where the music scene is and diving in. You're going to have to do that anyway, so why wait?
You're going to come out of college having spent tens of thousands of dollars for something that isn't worth very much at all. Your "connections" won't get you very far at all, because tenured professors aren't well connected. If they were, they'd be making a living gigging, not in academia.
If you're going to spend tens of thousands of dollars to build a music career, just move to where the musical opportunities are, take lessons, network, gig, get to know people because that's how you actually make a career, any career. The adage "It's not what you know, it's who you know"? There's a reason why it's an adage.
That said, formal training can be very useful, especially for a drummer. You'll learn to be a percussionist. Is it useful enough to drop >$50,000 on? Not in my book. You can get those skills from private lessons for far less cost, while living in LA or Nashville or New York, and playing/connecting with the people who will actually pay your costs of living. You're going to end up doing that anyway, so why start with a financial monkey on your back? From what you've written, that's what you're viewing college as: A networking opportunity with the bonus of picking up some extra musicianship.
I don't think that's worth all that money. But hey, it's not my life.
Look at it this way: You're starting a small business. You're an independent contractor (or consultant, if you prefer that moniker). A wise businessperson starts her business with a sizable chunk of money. That's called "capitalization." It's what you live on until the business takes off. If she does that, she has a greater than 70% chance of success.* If she starts her business with debt instead of capital, she has a less than 10% chance of success.
Let that sink in for a moment. Less than ten percent chance of success. No matter how good she is at whatever she does. Her debt will sink her.
In my opinion, this impulse of "IMUSTGOTOCOLLEGE" is a huge mistake. It's an industry selling a product. It's hype. It's not necessary - most jobs/careers don't need a university education. More troubling, university education is viewed as a career-training program, which is most decidedly not (sadly you appear to have fallen for this hype). Most troublesome, it sets up the most vulnerable - young people like you - with a huge amount of debt when they're just starting their lives.
If your parents have saved enough to stroke your institution of choice a periodic check, you're better off getting them to sign a lease on an apartment in your musical scene of choice and giving you a monthly allowance for the four years you'd otherwise spend in school. That way you won't have to slave at some bullsh!t job to make ends meet while you're building your business. That's an example of proper capitalization of your small business. ;-) Even if they haven't saved much (or anything), they're better off paying you to do what I describe. Work out a deal with them to pay off their investment. That's what a businessperson does.
All that said, provided you actually avail yourself of a high-quality liberal-arts university and apply yourself assiduously therein, you will emerge a better, more enlightened person. A liberal-arts education is a wonderful thing. But be aware that that takes application and energy on your part. You can't stay holed up in the School of Music building all day long. That might as well be 13-16th grade. You need to take eclectic elective classes, read Descartes, investigate the behavior of quarks, understand macroeconomics, figure out iambic hexameter.
A liberal-arts education means you dip into as many different disciplines as you can find, and learn enough to be conversant. Not an expert; leave that to those who major in those fields. But enough that you can talk to an expert at a cocktail party and not embarrass yourself.
When you add all that up, it means hard questions: How much is a liberal-arts education worth to you? Do you even care about any of what I've described?
Or are you looking for a career-training program? A liberal-arts education is about exploration, broadening your intellectual horizons, expanding your personal universe. If you're not into that, if you know what you want to do, then I cannot imagine why on earth you'd waste four years and the better part of a hundred grand on a liberal-arts university or indeed any institution of higher learning.
