Hi Scott, and thanks for your inquiry.
A 2.2 is definitely going to present some challenges for you. Definitely a good GMAT will help (and the higher the better in your case) and if you can start building an alternate transcript (taking night, weekend or online classes in rigorous subjects and doing well in them) that will also show the committees more recent academic success. Applying part-time gives you a little more flexibility as well, since the schools often have a broader range for what they accept for part time applicants. Yes, excellent recommendations, activities, and work experience will help, but the schools need to feel confident of your ability to thrive academically.
The other caution is your statement that you're looking to change careers completely. While schools do understand that a lot of their applicants are career changers, they still like to see a logical flow from what you've done to what you want to do. If you can think about transferable skills - what skills has your music career given you that may help in your future career (e.g. ability to deal with difficult conditions on the fly, ability to work with artistic temperaments, discipline and rigor, etc.) - then your personal statement should show how your future will build on your past, even if it's in a completely different field. (On our website,
www.mbamission.com, there's a link to a free Personal Statement Guide that discusses this concept of logical flow).
Best of luck,
Jessica Shklar
