Most people know Mark Fell and Mat Steel under the name SND. Like no other project before, they stand for the propagandized clicks-and-cut sound. They toured with Autechre and released two records in 1999 as Blir. The minimally-designed covers and the anonymous layout reveal that Blir as well as SND are names of projects rather than names of a band. Blir was always meant to be an open platform. Mat and Mark had been working in the surrounding field of Sheffield University where they first met Autechre in the early '90s. Together with Jeremy Porter and Robert Baker (Premium Leisure), they set up a collective of artists in order to do recording sessions, start radio projects (Non Axiomatic) and exchange synthesizer patches with Raster-Noton's Frank Bretschneider. Blir was part of the notion of an anonymous techno collective. In 2005, the project continued. Probably not as anonymous as they would like, Mat and Mark return to their roots while relocating old session material and cutting and re-editing it in a new way. Blir pursues a more radical approach than SND does. There is no format of a song, the arrangement is minimal. Music structures are cut into short loops, are analyzed and kept -- efficiently and energetically.
