Steinway & Sons has been manufacturing concert grand pianos for 150 years. To commemorate this anniversary, Karl Lagerfeld has designed an instrument that is unequaled in terms of beauty and sound: the Steinway Limited Edition, or S.L.ED. For the first time in the history of grand piano manufacture, Lagerfeld has rethought the traditional form. By shaping the feet like the runners of a sled, Lagerfeld has given the piano a new silhouette and has simultaneously made substantial improvements in the instrument's resonance. This book documents the creative process involving the S.L.ED from the first drafts and color tests through the various production steps in the Hamburg Steinway factory to the finished instrument. It's a sensorial study of function and design and a convincing new interpretation of a classic shape.
