Jon Burlingame editorMichael Giacchino’s dark symphony for “The Batman” — from his brooding theme for Bruce Wayne to children’s choir for the Riddler and noirish stylings for Catwoman — is the year’s most talked-about score and among his most ambitious yet.When Warner’s WaterTower label released a “Batman” track in late January, it racked up an astounding 2.3 million views on YouTube — the highest global streaming engagement the label had ever seen for pre-release from a score album. And interest has only grown in the weeks since the subsequent teasings of more Giacchino music and Friday’s release of the movie.“Michael brought soul, he brought dread, he brought all of the emotional and atmospheric undercurrents that a movie like this requires,” director Matt Reeves tells Variety.
