I don’t remember whether she looked at Berklee (probably she did.) Here’s why she chose Mills:
In almost every other college and university, if you look at what the Music department teaches and studies it means exclusively classical music and almost entirely pre-20th century classical music.
The Mills graduate music program, on the other hand, includes the Center For Contemporary Music, which incorporates the archives and history of what was once the San Francisco Tape Music Center, founded back when “electronic music” mostly meant musique concrete . Its alumni include (for just a few examples) Laurie Anderson, Dave Brubeck, Phil Lesh, Steve Reich, Greg Saunier (Deerhoof), Morton Subotnick and former and present faculty include Darius Milhaud, Pauline Oliveros, Morton Subotnick, Fred Frith, etc. They have - as you might expect from that list - a heavy emphasis on modern techology in music, avant-garde composition, and improvisation, and they also teach recording engineering.
My daughter went in there knowing a couple instruments but basically too shy to play in front of anyone, not feeling she had any talent in composition, and figuring she would study music engineering and production. By the time she left she was playing confidently in several bands, able to improvise well on a number of instruments, and composing electronic music, and got electric bass lessons from Fred Frith along the way. Win.
