“The only true impulse is realism,” wrote Philip Guston in 1972. “Arty art screws you in the end; always be on guard against it!” In 2020, the exhibition “Philip Guston Now,” which focused on the artist’s challenging late paintings—the ones containing cartoon-like depictions of hooded Klansmen—was postponed due to its sensitive material. It eventually toured to four museums, beginning in 2022. Much of the work of Guston’s last years (he died in 1980, at 66) confused the art world, and even cost him some respect. Gone was his alignment with Abstract Expressionism; instead, he opted for a harsh and more realistic form of figuration. The exhibition “Philip Guston: Singularities” was co-curated by Guston’s daughter, Musa Mayer, who adds a personal perspective to the paintings created between 1968 and 1979. Her choices for the show include works that the public has yet to see, as well as some of Guston’s best-known pieces. —Zack Hauptman
