“Eastman is heaven for instrumentalists, but students also get to study at the University of Rochester, of which it is a part. It’s perfect for aspiring musicians who don’t want to sacrifice academics. That’s why bassist Erin McPeck of Aurora, Colo., chose Eastman; she’s now planning a scholarly career in music research while working as a physics teaching intern at Rochester and participating in Eastman’s Institute for Music Leadership. Applications were up 10 percent this year, more than the national average.”

Meanwhile, Curtis (in Philadelphia) is free, if you’re able to get accepted to it. Otherwise, rflskt gave you an excellent list.
