Seth Tsui has scored 15 feature films, 4 video games, and co-produced 3 sample libraries. Currently he is working full-time for Riot Games as Music Composition Supervisor in their Singapore Studio.

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:

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 2013 Marvin Hamlisch Film Scoring Competition for Emerging Composers.

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.”

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 continued to score 3 features in total for Skyline including the popular "Kung Fu Pho" and critically acclaimed "12 chòm sao: Vẽ đường cho yêu chạy."

After Skyline Inc stopped producing new films, Seth decided to do break into scoring for his favorite medium: games. He made a VR game demo based on the classic novel War of the Worlds and showed it on a Samsung Gear VR while waiting in lines at GDC. Though this did not net him a job in gaming, he was able to hear the same complaint from all the US game developers he spoke to: all the game development jobs were moving overseas, to China.

Seth thought, “well, I can move to China!” so in August of 2016 he did. His first gig there was 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 gameshow app 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 media production district.

In 2019, Seth scored a Chinese animated film with live orchestra and choir on every cue (75 minutes of music) “Monkey King: The Journey Begins” for Red Dragon Entertainment. He chose Four For Music as the orchestra for Monkey King, and conducted all the sessions himself in Sofia, Bulgaria. There he met George Strezov, leader of Strezov Sampling, who asked him to co-produce the largest Chinese instrument sample library ever made, JADE Ethnic Orchestra. Seth recruited players in Beijing of every Chinese and Mongolian instrument and personally conducted the recording sessions which spanned almost a year. Following the overwhelming international success of JADE Ethnic Orchestra, Seth collaborated with Strezov Sampling and the same musicians to create his “signature” collection of evolving soundscapes, JADE Evolutions.

In 2020-2022 Seth wrote music for China’s most popular game 【王者荣耀】Honor of Kings, when they asked him to write theme music and score the 8-minute animated trailer for their new character “Lan.” During this time Seth also scored 5 major Vietnamese films: “Kumanthong” “SURVIVE” “Vietnamese Horror Story” “MUOI: The Curse Returns” and “Dao Doc Dac.” Seth scored 5 of DJI’s leading product launch commercials, including the Mavic Air 2, Robomaster S1, and Osmo Mobile 3-4, and wrote over 1.5 hours of music for the mobile game “Revived Witch.”

In 2023, after a grueling 4.5 month interview process, Seth won the job of Music Composition Supervisor at his favorite game company, Riot Games. He has just completed his first year working at Riot, where he composes music for League of Legends and Teamfight Tactics in addition to supervising in-house and outsource composers to create music that fits Riot’s world-building and standards of excellence.

Seth lives in Singapore, and when not writing music, he can be found performing on jazz trombone with various bands, playing League of Legends (Wukong jungle main), SCUBA diving, and brewing his own beer.
