The show’s theme song, which comes from Emmy and Grammy-winning composer Danny Elfman, who created iconic theme songs for “The Simpsons” and “Wednesday,” was given free rein.
“As you watch the series, he kept changing it! It’s not the same song in every episode and he messed with it on purpose,” explains Lorre.
There is also an array of music genres heard throughout the show, with artists ranging from the Talking Heads to Willie Nelson.
“Danny also recommended the amazing composer who scored the episodes, Joe LoDuca,” says Prady. “He adds an amazing color and texture and he’s writing in different genres because the worlds are different. Our music and post production people also suggested some wonderful needle drop music.”
