Seth Tsui began his career as a trombonist, studying not only the orchestral repertoire, but also building his skills as a virtuoso soloist and jazz artist. Hear one of his live performances:

After earning his music performance degree from DePauw University, Seth focused his efforts on Rock Music, writing, singing, and recording two albums under the band name "Addictive Stranger" and touring nationally to perform it live:

Between tours with Addictive Stranger, Seth became fascinated with the music of Asia, and undertook a study of the Chinese Erhu, as well as learning several middle-eastern instruments for his work with the Silk Road Ensemble.

Following the urging of several colleagues who agreed that Seth's music would fit best in films and games, Seth moved to Los Angeles and began writing for independent films. His major breakthrough came when he won first place in the Inaugural CINE Film Scoring Competition for Emerging Composers (now the Marvin Hamlisch Film Scoring Competition).

With his success at smaller productions, Seth began looking for jobs on big budget Hollywood productions. He became Heitor Pereira's lead technical assistant, where he worked on some of Hollywood’s biggest films like “Minions” and “If I Stay.”

It was then that Skyline Inc, a major Vietnamese film production studio, became interested in Seth's work, and asked him to score their first feature film, "Chung Cu Ma." Seth has scored 3 features in total for Skyline including the popular "Kung Fu Pho" and critically acclaimed "12 chòm sao: Vẽ đường cho yêu chạy."

In August of 2016, Seth made the biggest decision of his career, to move to China. He began as the in-house composer for Babeltime Inc, working on their mobile games such as Iron Blood Fleet【铁血舰队】and in the following year, he composed the music for China’s most popular mobile game at the time, 【冲顶大会】including its memorable theme.

In 2018, Seth was the lead or sole composer for 4 feature films in China, and hand-built his dream studio in the heart of Beijing’s GaoBeiDian movie district. He is currently the composer for Red Dragon Entertainment Ltd on several of their new animation properties, including the much anticipated Monkey King: The Journey Begins.
