Exai

Exai is the eleventh studio album by British electronic music duo Autechre. It was released on 7 February 2013 through Warp Records, with physical versions arriving on 5 March 2013. Prior to the release of NTS Sessions 1–4, Exai was Autechre's longest album.

Sean Booth and Rob Brown experimented with something they call "the system", a large network of software and synthesisers, during the creation of Exai. Critics responded generally positively to the album, noting its complexity and its use of sounds from previous albums. Some criticised the selection of tracks on the album and their length. Exai was followed by a companion EP named L-event which released on 28 October 2013.
