Charles Mingus: Mood Indigo
Let's take a moment to appreciate one of the least renown colors of the rainbow. It's not a primary color, or even a secondary one, but it's one we couldn't live a full life without. I'm talking about indigo, that mysterious lady of the night who bridges the gap between blue and violet.
This song's composer Duke Ellington knew the power of indigo, a color even "bluer" than blue itself. The bottom lines is that you ain't been blue until you've had that mood indigo. It's not a pushy color, but it can bring you down just the same, right down to your shoes...
For a standout vocal version, try Frank Sinatra's stellar rendition on Wee Small Hours. (When you've loved and lost like Frank has, you know a little bit about the blues, and indigo moods.)
