Kristin Robinson Forrest Frank, 25, and Colin Padalecki, 23, who make up rising duo Surfaces, are the unlikely hitmakers behind one of the hottest songs of the summer, “Sunday Best.”While it seemingly came out of nowhere, the song was, in fact, made in a dorm room — more specifically a closet — belonging to Padalecki at Texas A&M University. It’s hard to believe that, from there, “Sunday Best” would begin its slow build to ubiquity, now closing in on half-a-billion plays on Spotify alone.
