About a month ago, when 2013 was a near-blank slate with nothing but a week’s worth of scribbling on it, I posted a song by Richmond-based musician Stephen Frost. It was called “Age Of Gold,” and its release was accompanied by a YouTube video in which Frost pulled back the curtain to reveal how and why the song was created. Being the backstory junkie that I am, I was more than a little intrigued by this formula. Hearing a bright and engaging song and immediately looking under the hood to find out what makes it work so well? That’s about as good as it gets, and it’s precisely the recipe for Frost’s nascent “Paris Métro” project, which recently saw its second installment — the considerably darker “Wimyn Redux” — hit the Internet. I was so excited that I asked Frost if he would answer a few questions via email about the new song, his approach to writing and recording, and his plans for the Paris Métro project going forward.
