The album is the first album released by label Non Standard, a record label created between Hosono and Teichiku Records to release the technopop/hip-hop styled material he worked on.
The 1988, 1993 and 2001 reissues of S-F-X contain tracks from Non-Standard Mixture, an EP created by Hosono the same year as the album.
