DSCI4 is a UK drum and bass label founded by Trace and Nico in the late 1990s. Its sound comes out of techstep, which Trace also called technoid drum and bass, and the name is a play on the word "decipher". The label set out to release music by both new producers and established artists, with records from Stakka & Skynet, Teebee and Calyx.
Its Spy Technologies compilation series included a 2002 edition with artists from several countries. Mindscape's Highway EP came out in 2004, and on 8 February 2016 the label issued Rice Bowl / Tachyon with tracks by Gremlinz & Adrian Go and Quartz featuring Nanobyte. HLZ's Rust EP followed in 2025.
