I am mostly familiar with UCLA and U Mich. Both have excellent, highly competitive programs. And needless to say both have required auditions. (all good performance programs do have auditions)
What exactly are you looking for? Are you looking for a program that does not require an audition? Are you looking to major in performance? What particular instrument? Or are you seeking a school where you can participate in music but not major in it? BTW—all music departments list audition requirements online.
