With a focus on live performance and a growing international collection, the new Tate Modern seeks to reinvent the way audiences engage with art, with Herzog & de Meuron’s striking Switch House extension increasing the gallery space by 60%. Director of Tate Modern, Frances Morris, explains ''The spread of work from different parts of the world is remarkable – over 50 countries are represented across a wide range of media. And for the first time we have galleries that really respond to and complement the way artists work now. These new displays allow us to situate our iconic artworks – the Rothkos, Rileys and Richters – as part of a wider international dialogue.'' Sotheby’s took a closer look inside ahead of the opening on the 17th June – from the panoramic viewing level atop the ten-storey extension, with 360° views over London – to the subterranean oil Tanks that will host the opening weekend’s performances by artists Roman Ondák, Tania Bruguera and Tarek Atoui.
