Autechre's catalogue is as maze-like as their convoluted beats. The UK duo has gone from the spooky electro and ambient of early albums Incunabula, Amber and Tri Repetae to the hyperkinetic flux of later records like Oversteps and Exai. Along the way, they've trafficked in erratic laser blasts, glitch-ridden software experiments and noise-encrusted B-boy jams.
