The duo of Sean Booth and Rob Brown have been making music together for almost 25 years, hooking up over a mutual love for graffiti, hip-hop and electro music, trading mix tapes and eventually collaborating under the guise Lego Feet. Their first release under the Autechre (pronounced aw-tekk-urr) moniker would be 1991's Cavity Job, and the rest, as they say, is history.
This 1995 release, Tri Repetae, is a decent barometer of Autechre's ouevre; it's right in the mid-point of their earlier, more accessible work (the LPs Incunabula, Amber and the Anti EP) and their move towards a freer, more experimental approach (the albums LP5 and Confield, as well as the arc of their trajectory until present day).
Their advancement of glitchy, techy and ambient soundscapes has contributed to the growth of IDM as well as influenced many imitators- I'm almost kicking myself for not discovering this wonderful music earlier.
