Frieze London returns to Regent’s Park for its 21st year. The programming is robust, with a mix of up-and-coming artists and long-established creators from over 100 galleries, including London’s avant-garde Emalin and Thomas Dane. If you prefer the classics, this year the fair coincides with Frieze Masters, which also includes more than 100 galleries spanning centuries of art. (Annabelle Selldorf is designing the floor plan.) Highlights include solo presentations of Kim Yun Shin at Lehmann Maupin, Beatrice Caracciolo at Paula Cooper Gallery, and Thaddeus Mosley at Karma, as well as the countless stimulating artist talks at both Frieze London and Masters. —Elena Clavarino
