TRSI is an acronym for Tristar and Red Sector, Incorporated. Founded by a supplier from Germany who went under the pseudonym Irata [1] (http://noname.c64.org/csdb/scener/?id=4380), TRSI began in 1990 as a cooperative Commodore 64 demo coding and cracking group. The alliance between Tristar and Red Sector, Inc. was formed after different group members met up at KewL Party in Denmark.

TRSI naturally migrated from the C64 release platform to the Amiga and IBM-PC, and even branched off into the console gaming scene. In the mid 1990s they created an independent record label, TRSI Records.
