The two hours of unreleased archival music was originally broadcast as two separate mixes on NTS this past weekend as part of Warp's three-day takeover to celebrate the label's 30th anniversary. The files are available for free download over at the AE Store. (You can find it at the bottom, or download directly here.)
As the title hints, the two-part mix features unreleased music composed in the UK duo's early days, from 1989 to 1993, and focuses on a much more dance floor-oriented side of Autechre.
