Our latest guest on Soundtracking is Eric Vetro, one of Hollywood's premier vocal coaches who's worked on the likes of Elvis, A Complete Unknown, Wicked and Maria, to name just some of many. As you know, we like to shine a spotlight on those people who don't necessarily get the wider acclaim they deserve when it comes to their importance to the filmmaking process. And Eric is one of those people, so it was fascinating to get a little insight into his role, and how it changes from person to person, project to project.
