For an opening, especially the launch of a beautiful brand-new exhibition space, every upscale gallery wants to gather together a gaggle of lovely, well-groomed faces wearing engaged and cheerful expressions. For the opening of his solo show with Timothy Taylor, one of London's top galleries, Alex Katz, Manhattan's master of urbane chic art, even installed his own ideal art opening crowd. The 1968 sculpture "One Flight Up" consists of a 67 by 18 inch chest-high platform holding a series of oil-on-metal cut-outs of sophisticates in conversation. Katz rarely shows his sculptures, but the new Timothy Taylor gallery in Mayfair was designed by Eric Parry in a former bank, so it's an ideal space to show the gallery's roster of blue-chip artists. At the same time, Emma Dexter, the gallery's new Director of Exhibitions and formerly Senior Curator at the Tate, will show a series of emerging-artist group exhibitions at the gallery's old Dering Street venue. Demonstrating his support for the young crew of artists whose work can be seen in "Enter the Path" at the Derring Street gallery, Katz attended the gallery's Saint John's dinner with his chic wife and muse Ada, the woman whose easy, eternally elegant style Katz has documented in his iconic portraits for over fifty years.
