This two volume set surveys the first 30 limited editions put out by En/Of since 2001. Each En/Of edition takes a rigid format where a visual artist creates work to be contained within the 12" x 12" border of an LP cover while the musicians must make a recording on vinyl. The first half of the set contains edition descriptions and artwork reproductions as well as an exhibition history and essays by Jorg Heiser and AA Bronson. The second half of the set contains musical works taken from the editions on three CDs in a foldout cardbord box. Includes contributions from numerous artists including Franz Ackermann, Doug Aitken, Darren Almond, Tacita Dean, Thomas Demand, Sam Durant, Olafur Eliasson, Elmgreen & Dragset, Liam Gillick, Dan Graham, Carsten Höller, Jonathan Monk, Sarah Morris, Tobias Rehberger, Gerwald Rockenschaub and Simon Starling.
