Jang Dal Im was born in Keelung, Taiwan and is a second-generation Korean expatriate. His father is Korean, who moved to Taiwan working as a fishery engineer, and his mother is Japanese. In 1986, at age thirty, Jang Dal Im founded Crystal Records, which began as a publisher for Rocker (one of the very first Taiwanese magazines on Western music), and later acted as an agent for well-known British Indie music brands such as Rough Trade and Factory, gradually becoming a legendary brand among Taiwanese music fans. Crystal Records plays a significant role in introducing Western music into Taiwan, allowing locals to  get a glimpse of what the outside music world sounded like back in the days.

Aside from acting as an agent of Western music brands, Crystal Records is also devoted to producing Taiwanese local music and hosting the so-called Taipei New Music Seminar for several years. Many well-known musicians of today, such as Wu Bai (伍佰), Ming-chang Chen (陳明章), Blacklist Studio (黑名單工作室), Jutoupi (sometimes Jutopi) (朱約信 aka 豬頭皮),  Summer Lei (雷光夏), Kay Huang (黃韻玲), Will Lin (林暐哲) and many others were either discovered by Crystal Records or took part in concerts hosted by them. Jang Dal Im, along with his associates in Crystal Records, even used their civic power to help create Taiwan Audio Database, Taiwan Underground Voices, The Series of Roles and many other music or audio recordings. These invaluable audio works documented and preserved many beautiful sounds of Taiwan. Always striving to stay true to their own motto, “Finding your crystal heart despite the world’s profanity,” despite going through bankruptcy multiple times, Crystal Records never gave up, using all their power and funds to help establish a different yet better path for Taiwan’s local music industry.

Jang Dal Im is fluent in Korean and Japanese and familiar with Korea’s political and socio-cultural status. He established TEAMS Project  (Trans East Asia Music Society Project) and has been invited to Gwangju, South Korea (a city known for its civil rights movements) for seminars and talks, discussing and sharing thoughts on how Korea can work and cooperate with Association of Southeast Asian Nations (ASEAN), and how to build up Asian pop music culture and create platforms for audio databases. In recent years, TEAMS Project mainly focuses on research and application of blockchain technology. By using this innovative technology on digitized data transactions, the team hopes to recreate and redefine the market of the music industry and also return to the diverse essence of music, art and cultural creation.
