Bob Lydecker has always been musical, according to his mother, Wyn, of Darien.
In third grade, he began singing in the church choir at the First Congregational Church.
"He told me he could read the notes in the hymnal before he could read the words," his mother said.
Years later, the Darien High School graduate, now 23, is making a name for himself in the music industry thousands of miles from home. Lydecker contributed music to the score of the new film "The Crazies," directed by Breck Eisner and starring Timothy Olyphant, which opened on Feb. 26, and was No. 3 in the box offices during its opening weekend.
Lydecker worked for Grammy Award-winning, Oscar-nominated composer Mark Isham, who composed the movie's score.
"[Isham] wrote the music and he came up with the themes and all of the musical ideas that are used for the film, like deciding what instruments and what sounds are used," Bob Lydecker said. "Using his music as a foundation, I scored some of the other scenes."
Lydecker's music was mostly electronic, with percussion he said, but he has worked with several kinds of music and instruments.
"I took him to a string quartet at Norwalk Community College when he was in high school," his mother said. "He heard it and came home, and started composing a string quartet."
Lydecker was a member of a punk rock band during high school, and gravitated mostly to drums and guitar. He also participated in the Idea Program when he attended Darien Public Schools.
"I wrote a different piece of music in a different style every month," he said.
It was great preparation for his work on the film's score, which he described as a "daunting, fast-paced" task. Some days, he woke up at 5 a.m. and worked until the afternoon, before taking a break in the afternoon and returning to work from 9 p.m. to 2 a.m. But he has no complaints.
"It's the kind of thing I would just be doing, just making music, even if I wasn't doing it as a career," he said. "It's not something I consciously made a decision about. It's an expected part of my life."
He's currently working on a few new projects.
"Nothing big right now," he said. "I'm working on some independent short film, a student film at the University of Southern California, a TV pilot and two Web series."
USC is his alma mater. After graduating from DHS in 2004, Lydecker he attended the university, earning a bachelor's in music composition in 2008, and a graduate certificate in scoring for motion pictures and television in 2009.
He gravitates toward working with music for the positive effect it can have on an audience.
"I feel like in my life, I want to do something where I can have a positive effect on the world," he said. "Maybe doing music for "The Crazies" won't have that kind of impact. But at the same time, maybe someone's having a bad day and they can watch the movie and have an enjoyable experience."
His family in Darien went to see the film on Saturday, a day after its world-wide release.
"It was so exciting to see his name in the credits," his mother said. "We're really excited and really proud."
