Autechre has always divided opinion. There are those who consider them geniuses; mavericks who make out-there computer music that simultaneously sounds like a riot in a steelworks, and an argument onboard the International Space Station. Others are less kind, but then their particular brand of crunchy IDM and leftfield electronica is undoubtedly an acquired taste. Exai, their 11th album, stretches out over 17 tracks. As ever, it packs in a lot of ideas, a swathe of mentalist rhythms and a boatload of curious noises. At times it's strangely calming, at others like being smashed round the chops with a metal bar. Those who enjoy their work - and we certainly do - will find much to enjoy amongst Exai's sprawling, feature-length presentation.
Battles have always operated at the fringes, in a place where rock and electronic music meet to get it on. On this occasion, it sounds like the chosen remixers have tipped the balance in favour of Battles's techno leanings. The Qluster version of "Dominican Fade" is closest in sound to the act's own approach, with dreamy synths spiralling to a climax against a glitchy backdrop, but it's all about the straight four/four material here. Kangding Ray's take on "Toddler" is a sumptuous dub techno groove, while Silent Servant's version of "Inchworm" is all about the humming, pulsing bass and rattling percussion.
