Jazz Tangcay Artisans Editor Netflix’s new series “Agent Elvis” arrives March 17 and sees the King of Rock ‘n’ Roll pulling double duty as a singer by day and a secret government battling dark forces by night. And this time, it’s Matthew McConaughey voicing the King. Accompanying the animated series is a musical soundtrack composed by Tyler Bates and Timothy Williams, who recently scored “Pearl.” Intertwining iconic Elvis Presley syncs such as “Viva Las Vegas” and “If I Can Dream” is a score with a rock-tinged surfer vibe and plenty of guitar to underscore the action. Says Bates, “‘Agent Elvis’ is such an amazingly hilarious show that Tim and I had to tamp down our laughter in order to work on the score, which is a musical odyssey unlike any I have previously encountered.”
