Boston Globe has a feature on the program, which this semester includes five classes in game audio and scoring (in a musical sense). The piece covers the basics of the program, from the first class started four years ago to the compositions being put together for local indie games. Berklee isn't the only school with video game audio classes, as Yale, New York University and local rival New England Conservatory also feature programs.
The thing that really makes Berklee stand out, however, is its Video Game Music Club, which reportedly has 300 members. Check out the Globe piece for a nice introduction to Berklee's growing recognition of the medium.
