Music schools aren't just about performance - as long as you are clever about what your research field is, any degree is applicable to any kind of career. Want to go into politics? Write a dissertation on the political influences of the Habsburg monarchy on European music, or perhaps unearth new data on the fly-over republican states through an ethnomusicological lens. Want to get into technology? There is probably no more fun way than to do a PhD in sonic arts, creating complex technical-marvel music machines and writing music software that lands you a job with one of the many music software companies (or start your own). Maybe you want a teaching career? Sure - it's hard work to get tenure but what could be more rewarding than talking and thinking about music all day. Sports or therapy? Music therapy in combination with Feldenkrais or Alexander techniques gets you into a more interesting, unique field than just standard therapy. I could think of a lot more examples how a music school could really supplement the career of anyone - it's the fault of the music school that focuses on looking backwards and only celebrating chamber/choir music. Many schools are realising that's not helpful anymore and while believe me, I love a great rendering of an 18th century opera, you can get a lot more out of music school than that.
