Jad Abumrad is a composer and radio producer living in Brooklyn. He's written music for film, theater, a smattering of remixes, and he's also the host and creator of the cult-hit radio series Radio Lab, which reaches over a million people a month. He also composes much of the music for the program. Growing up in Tennessee, Jad didn't have a whole lot to do, so he stayed in his room and composed music for imaginary films on four-track cassette. What he does now isn't so different.
