Universal Indicator (collective)

Universal Indicator is the group name for Rephlex Records artists Richard D. James (as Martin Tressider) and Mike Dred (a.k.a. The Kosmik Kommando). The name is a reference to the signature acid techno sound found on all the releases. Five projects were released, and a compilation CD was mixed by Dred.

All the albums are named after different colours used on the UI spectrum. Their catalog numbers reference Roland synthesizers: the TB-303, the TR-606, the MC-202, and the SH-101. They were released in the following order: Blue, Red, Yellow, and Green. Blue and Yellow were produced by Dred, while Red and Green are often attributed to James, though never officially. A fifth, released directly under Mike Dred's alias, expands the colour spectrum theme beyond the visible spectrum into Ultra-Violet.
