The line between music and sound can sometimes be incredibly thin, and so I think it is worth noting the recently launched Minnesota Public Radio series of interviews with video game music composers that exposes some of the process and insight behind the scenes presented in tersely edited podcast format. The series provides some great background on game music in general as well as, in the case of the Jason Graves (DeadSpace 2) Interview, the implementation side of thing:
“What makes the music so great in any game, is the implementation….and having it be as interactive as possible. Especially with horror it’s really important that you have the music come in, start and stop, make you jump, make it suspenseful and on the edge of your seat. The timing has to be just right.”
Other additions to the series include the folks from Double Fine talking about the classically leaning Stacking, and Inon Zur and Dragon Age 2.
