In part four of our exclusive interview with composer Dave Huizenga, we learn about Huizenga's main challenge in creating soundtrack music for A&E's Cold Case Files. That challenge? Writing music that speaks to the viewer without pulling them out of the story on the screen. Huizenga also talks about and demonstrates his Tascam GigaSampler and shows how he uses it in his daily soundtrack work. Gearwire editor Joe Wallace gives us a behind-the-show look at Huizenga's life in the recording studio.
