O’Brien is an accomplished Composer, Musician and Producer with over 30 years professional experience. He is particularly known for his dramatic scoring in Orchestral and Contemporary styles. He has worked with many veteran Producers and Directors on diverse Film and Television projects. Although his name is not yet widely known, his music has heard by millions every day in the United States. Since 1994, O’Brien’s work has been used in countless nationally broadcast spots by the CBS Television Network.
O’Brien has worked with a wide variety of studio ensembles – large and small – including the London Symphony Orchestra at Abbey Road Studios, London. Daniel marked his debut with the London Symphony Orchestra in 1996 with a world premiere performance of “The Pleiades” and the presentation of his award -winning “Colorado Suite.” Noteworthy among his film credits are original scores for the independent films “Brights” and “Last Train Out.” The latter film was honored at the Chicago Latino Cinema International Film Festival and excerpts from its score were premiered at the Los Angeles County Museum of Fine Art in 1994 with O’Brien as featured guitar soloist. This performance was broadcast live on KUSC radio. “Michaela’s Theme” and “Grand Theme” earned O’Brien the BMI/UCLA Film Scoring Scholarship earlier in his career. The works were inspired by an original piece the CBS Television Network commissioned O’Brien to write for promotional use for the hit television series “Dr. Quinn, Medicine Woman.” O’Brien’s ability to compose in a variety of musical genres–from orchestral underscoring to “pop” styles including rock and contemporary ballads–has kept him in demand scoring films, television pilots and commercials.
An educator, O’Brien was the Director of Instrumental Music at Oak Park High School for six years where he conducted the Concert Band, Wind Ensemble, Orchestra and Jazz Bands. He has also taught AP Music Theory, Music Production and a course on the History of Rock & Roll.
