I was going crazy trying to think of where I'd heard that music from the dream sequence in Mad Men's 'The Fog' episode. Turns out I wasn't the only one. I had been wrongly guessing Tchaikovsky. It turns out to be from one of my favorite films, Sex and Lucia (up there with Cinema Paradiso), by one of my favorite film composers, Alberto Iglesias. Why couldn't I remember that!? If you haven't seen it yet, you're missing out big time.
