Spanish artist Jaume Plensa is celebrated internationally for his tactile, inquiring sculptures and installations. He is best known for his large-scale public pieces, which include Dream, created for St Helens and supported by the Art Fund, Breathing, which sits on top of Broadcasting House and Crown Fountain in Chicago's Millennium Park.With its uniquely flexible gallery and outdoor spaces, Yorkshire Sculpture Park is able to display not only some of Plensa's recent large-scale sculptures, but also his drawings and interior pieces. On show are a 50-metre curtain of poetry made of suspended steel letters, semi-transparent figures in the landscape, fibreglass suspended 'angels' and large illuminated heads radiating white light.Plensa uses metal, resin, stone, light, sound and text to create works that establish a democratic dialogue between art and environment. The sculptures not only invite but demand the interaction of their audience, who become co-creators with the artist. They blur the edges between art, nature and language, prompting viewers to look differently at the architecture and landscapes of their daily life.
