Introducing the annual Art and Design issue — a celebration of creativity and vision. Fronted by the incomparable Lenny Kravitz (shot in his Paris townhouse), in this issue we talk to Arthur Brand, the world’s finest art detective; step inside the otherworldly creations of architect Ricardo Bofill; meet the young men behind the country’s most innovative (and ancient) family seats; and introduce the Tastemakers — London’s 50 most influential artists, gallerists, designers and curators.
