Frieze New York opens to the public today on Randall’s Island. We perused the preview on Wednesday to round up eight top sights you won’t want to miss. Canada One of the earliest artists on Canada’s roster, Katherine Bernhardt in many ways shaped the gallery’s aesthetic. Her exuberantly loose paintings — distant relatives of fellow gallery artist Joe Bradley’s — are unmissable at Canada’s booth, which she curated and whose floor she covered with a colorful patchwork of Moroccan rugs.Galerie LelongArtist and Harvard professor Krzysztof Wodiczko made only five of his “Homeless Vehicles” in the 1980s, for which he interviewed homeless New Yorkers about the features they would like to see on a utilitarian cart. The result is a long, tented vehicle with a sleeping area, a seat, and a basket for collecting cans. Galerie Lelong has the only version on the market — the other four are in major museums — along with a drawing and video of the work being used on the streets of New York.PPOWTwo 1980s artists, David Wojnarowicz and Betty Tompkins — one a fallen star and the other belatedly rising — appear in harmonious tandem at PPOW. Tompkins’s confrontational text paintings bear words like “coquette” and “chica,” while Wojnarowicz makes an impression with a striking installation of a boy caught on fire, apparently running away from the New York City skyline.Marian GoodmanA selection of William Kentridge’s blocky black ink and charcoal drawings reveal the process behind the South African artist’s large-scale projections that were featured in a stunning production of Alban Berg’s “Lulu,” performed late last year at the Metropolitan Opera.Richard SaltounThe centerpiece of this notable historical showcase of work by the French conceptualist Robert Filliou — a contemporary of Marcel Broodthaers and Joseph Beuys — is a broom in a bucket, an homage, in part, to Marcel Duchamp. Recasting the Mona Lisa as a maid, a sign on a broom handle reads, in French, “the Mona Lisa is on the stairs” and, on the other side of the notice, “back in 10 minutes.”Andrew KrepsAt his best, the Detroit-born sculptor Michael E. Smith’s use of line and space appear as elegant as poetry. In this booth, a series of thin halogen lamps line up like a stanza on a pair of drooping gym shorts. Almine RechPeter Halley’s geometric paintings are not necessarily the rarest of sights at an art fair, but Almine Rech is displaying three especially eye-searing examples — and we mean that in a good way — of the artist’s neon grid paintings.Pace GalleryFred Wilson opens the fair with a prominently placed mini-retrospective, including the artist’s color-stripped African flag paintings, black glass drips, and a pair of figurative sculptures — one white and styled in Greco-Roman fashion, the other black and Egyptian. Other works not to miss: Anthea Hamilton’s commissioned performance-installation “Kar-a-Sutra”; Jessica Stockholder at Galerie Nathalie Obadia; Jean-Michel Sanejouand at Art Concept; Ashley Bickerton at Lehmann Maupin; and Betty Woodman at Salon 94.
