Cat System Corp.

Jornt Elzinga (born 1989), commonly known as Cat System Corp. (Japanese: 猫 シ Corp., Hepburn: Neko Shi Corp.), is a Dutch musician regarded as a vaporwave figure that originated the mallsoft subgenre. He also previously recorded as Mesektet for his dark ambient releases.

Born in 1989, Elzinga started his music career in the 2000s with drone and noise productions. He began his independent vaporwave career in 2013, and became popular in the scene with his 2014 album Hiraeth. His solo works, including albums such as Palm Mall (2014), Cosmopolitan Dreams (2016), and News at 11 (2016), are known for popularising mallsoft. His collaborations with other musicians also spawned successful albums within the community, including Corporate Mixtape (2014) and Building a Better World (2019).

Elzinga's music explores concepts of late 20th century capitalism, presenting ambient shopping center recordings characteristic of mallsoft. It also portrays specific events, such as an alternate history where the September 11 attacks never happened, or a fictional soundtrack to a retro fashion TV series. In 2019, he founded his own record label, Hiraeth Records. He is one of the best-selling mallsoft artists as of 2022.
