LONDON.- This autumn the Serpentine Gallery presents Philippe Parreno’s first solo exhibition in a public institution in the UK. Parreno rose to prominence in the 1990s, earning critical acclaim for his work, which employs a diversity of media including film, sculpture, performance and text. Taking the exhibition as a medium, Parreno has sought to redefine the exhibition experience by exploring its possibilities beyond a collection of individual works. Parreno’s exhibition at the Serpentine Gallery has been conceived as a scripted space in which a series of events unfolds. The visitor is guided through the Galleries by a timeline of orchestrated sound and image. Noise from Kensington Gardens is heard inside, as though the outside is leaking into the Gallery.
