I love inspiring stories of people like Dan Wallin who continue to push their creative comfort zones well into the later stages of their lives. So when I read about Danny (as his friends call him), the oldest working sound engineer in Hollywood, I was blown away for a number of good reasons. Dan Wallin is eighty-four years old and he recently finished mastering the sound track for Mission Impossible 4: Ghost Protocol. While he could be playing a lot of golf or enjoying twenty previous years of retirement, Dan Wallin continues to create, learn, and improve as a master of his sound engineering craft. Here’s my executive summary of the Los Angeles Times article, It’s Still Music to Dan Wallin’s Ears.
