  • Art Basel 2014

    16:10 PM - 25 Jun 14

    Despite competition from art fairs across the globe, Art Basel remains the premier venue for the exhibition and sale of Modern and Contemporary Art. No where else are the offerings of art equal to those on the the first and second floors of Basel’s hallowed Kunst Messe. Collectors from across the globe gather here to look at, discuss, gossip about, and very often, also buy art.   This year, the message seemed very much to be: look, think, discuss, then buy. While business appeared brisk and for coveted works there was the usual rush, in many other instances there was

  • Fall Gallery Openings 2013

    17:44 PM - 26 Sep 13

    The summer hiatus allows many habitués of the art world to escape for vacation, and to absolve themselves of art world responsibilities. The endemic fear of ‘missing out’ is allayed for a few short weeks. This comes to an abrupt halt at the end of the Labor Day weekend in early September, which marks the beginning of the Fall art season. Experienced by many in the art world as a ‘back to school’ moment, friends and colleagues reconvene at innumerable openings, dinners and drinks to celebrate new exhibitions and get up to date on recent gossip. While the heavy schedule

    Stonescape 2013

    16:47 PM - 1 Aug 13

    Every two years, Norah and Norman Stone organize a new exhibition of artworks selected from their private collection to be shown in a specially designed ‘Art Cave’ on their Napa Valley property, Stonescape. In addition to the ‘Art Cave’, an exhibition space excavated into the side of a hill, the property includes a farmhouse from the 1880s, a vineyard, a grove of redwood trees and other art works such as a sound piece by Alex Waterman and a Log Cabin sculpture by Cady Noland. This year saw the fourth exhibition since the space was inaugurated in 2007. Curated by Thea and

  • Art Basel and London

    18:31 PM - 21 Jun 13

    One of the most striking changes in the art world over the last forty years has been the rise of the art fair. From humble beginnings with the first ‘Cologne Art Market’ in 1967, the situation today makes an accurate count almost impossible, with certainly more than 200 art fairs, and probably many more. Within this storm of increased competition, Art Basel has maintained its importance and is still regarded as the most important art fair in the world. A huge array of satellite events cater to the enormous influx of art lovers that descend on this modestly sized Swiss

    Paris, Oslo, Venice Biennale

    17:00 PM - 10 Jun 13

    Travel has long been a valuable tool for the research undertaken by Art Advisory Services. To cover the European art scene, it is essential to meet with gallerists, curators and artists wherever they are based. With this in mind, Thea and Ethan spent time in Paris and Oslo before joining Suzanne and Ashley at the Venice Biennale. Paris is no longer the center of the art world, yet the high concentration of first class museums ensures its status as an important destination for art. At the Musée d’Art Moderne de la Ville de Paris there was a beautifully installed survey

    Frieze New York and May Auctions

    15:14 PM - 20 May 13

    Frieze New York returned for its second appearance on Randall’s Island – a small strip of land in the middle of New York’s East River rarely visited even by the most intrepid natives. The giant white tent especially built for the fair provided an open and airy space resplendent with natural light. With over 180 galleries it was inevitable that the quality would vary, but solo and two person presentations stood out. Roe Ethridge and Pae White were exhibited together in a booth shared by Greengrassi and Andrew Kreps. Murray Guy showed a remarkable series of photographs by Zoe Leonard

  • Previewing Jeff Koons at David Zwirner and Gagosian

    20:07 PM - 9 May 13

    With the opening of Frieze Art Fair this week, Thea Westreich Art Advisory Services had the great opportunity to preview the upcoming Jeff Koons shows at David Zwirner Gallery and Gagosian Gallery. Thea, Ethan, Suzanne, and clients of the firm visited the shows during installation. The visit proved to be very informative, with new works and an in-depth conversation with the artist. It is an exciting new body of work that heightens the anticipation for the upcoming Koons retrospective at the Whitney Museum in 2014.
