Mono, Dorothy?

I was thinking about the point in the film, The Wizard of Oz, when Dorothy finds herself “not in Kansas anymore.” The film conveys the magic by switching from black and white to colour at that point. A similar transition happened when the audio world moved from mono to stereo recordings, and again from stereo to surround recordings.
Recently, I felt a similar gestalt shift when recording score with an orchestra at the CBC instead of the usual sample libraries and synthesizers. You think you’re seeing the whole picture and then, BAM, you’re standing in technicolour OZ!
