A great composer whose music accompanied numerous Sci-Fi and other kinds of movies. He was often associated with James Cameron (Aliens, Titanic and Avatar) but Star Trek fans knew him for the best movie in the franchise, Wrath of Khan.
I have a couple albums of his stuff. James was quite distinctive from the other heavy hitters in the genre I love, John Williams and Jerry Goldsmith.
Better dig through my HD of MP3s (all derived from CDs and downloads I paid for!) see what what I have to listen to.
