He is the head of the film music division at DreamWorks studios and works with other composers through the company that he founded, Remote Control Productions, formerly known as Media Ventures. His studio in Santa Monica, California has an extensive range of computer equipment and keyboards, allowing demo versions of film scores to be created quickly.
