My friends and colleagues know well my deep passion for music. The office I packed up at BusinessWeek a few days ago featured large and dramatic black-and-white prints of Duke Ellington, Miles Davis, Dizzy Gillespie, Ella Fitzgerald, Billie Holiday, Louis Armstrong, and Frank Sinatra. So when I told them the name of my new company, C-Change Media, with the C referring to content, curation, and community, they universally suggested that I should have a theme song and it should be David Bowie's Changes. I couldn't agree more. So I found this terrific version of the tune on YouTube. Have a look and a listen and think C-Change Media when you do.
