I've been binge watching the first season of "Elementary" on Hulu. The score is absolutely incredible!! It's very nuanced and thematic. Why has this not been made available yet? Sean Callery has had other scores made available, "24" if I'm not mistaken? INMHO it's one of the best scores to a TV drama ever, and I really like "The X-Files" scores and the Ron Jones "Star Trek:TNG" scores.
He's not only actually worked with Snow before, but Snow was the originally announced composer for the series; undoubtedly he was too busy and suggested Sean.
