In late 2008 YES were asked by Warp records to create the identity for their 20th anniversary celebrations – Warp20. One of the first elements of the project is the forthcoming special edition box-set.
We pulled out all the stops to create something worthy of the label’s seminal status. The Warp20 (Box Set) consists of a heavyweight 10″ square slipcase wrapped in charcoal Buckram embossed paper with tipped-on gloss-laminated cover photograph. Contents include a 192 page book, Warp20 (1989–2009), featuring artwork of every Warp release. Two double CD albums and a one CD album, packaged in deluxe case-bound 10″ folders. Also included is a five vinyl set housed in uncoated card sleeves with debossed and foiled typography.
