Nexus 21 has been played over 30 times on NTS, first on 27 October 2014. Nexus 21's music has been featured on 30 episodes.

Mark Archer and Chris Peat from Stafford, England, had already worked together on various releases on the Blue Chip label when they finally teamed up as a duo and formed Nexus 21 in 1989. Also recording as C&M Connection in the same year with only one 12” release on the Blue Chip label, "Another Night", and two further tracks on Network, 'Biorhythms' and 'Flutes'. The first Nexus 21 release was "(Still) Life Keeps Moving", a vocal techno tune today regarded as an early classic. They followed this up with their outstanding sole LP "The Rhythm Of Life", which was strongly influenced by Detroit techno, but also included acid house, electro and breakbeats elements. After the release of the album, Blue Chip folded, and Nexus 21 found a new home in the just founded Network Records. Meanwhile, R&S snapped up "Logical Progression" and "Techno City" from The Rhythm Of Life and released them on 12”. KMS released a set of Detroit remixes of "(Still) Life Keeps Moving" by Carl Craig / Mark Kinchen / Kevin Saunderson. The first Archer / Peat releases for Network were licensed versions of Another Night and the Detroit remixes. Then the pair tried out yet another alter ego and released the "Overload EP" as Altern 8. They came back to being Nexus 21 for the deep techno of "Self Hypnosis", their contribution to the Bio Rhythm compilation. A remix of Self Hypnosis then appeared on the "Progressive Logic EP", alongside "Together" (from Bio Rhythm 2) and two tunes from The Rhythm Of Life, one remixed. A second Nexus 21 album was ready in late 1991, but due to sample clearance problems, the LP never materialized. A small edition of white labels of "I Know We Can Make It"/"Sychologic PSP" was released, which showcased a bigger hardcore influence. After the success of "The Vertigo EP" and "Activ-8", credited to Altern 8, Mark Archer and Chris Peat concentrated on that project. They still used the Nexus 21 name for occasional remixes.
