Honor deceased loved ones at Downtown Pittsburgh’s Dia de los Muertos celebration, visit Allentown for their Hilltop Halloween or check out “Frank Lloyd Wright’s Southwestern Pennsylvania: The Pittsburgh Projects” — here’s what to do in Pittsburgh this weekend.

Visual Art
It’s always worth a reminder that Pop Art master Andy Warhol was about more than soup cans, Brillo boxes and silk-screened Marilyns. The Warhol Museum’s new exhibit “Andy Warhol: Vanitas” mines the collection to reveal Andy’s overlaps with a genre of classical painting that recalled viewers to their mortality and to the fleeting nature of earthly pleasures. (Think skulls.) The show, curated by former Warhol director Patrick Moore in collaboration with the SCHUNCK museum, continues through March 9.

Festival
Downtown’s Día de los Muertos celebration starts this week. The Pittsburgh Cultural Trust festival centers on an ofrenda, or altar honoring deceased loved ones, by local artists Lisa DiGioia-Nutini and Alison Zapatta. The Thu., Oct. 23, kickoff lunch includes the ofrenda’s unveiling in Greer Cabaret Theatre, along with sugar-skull painting. Visitors can contribute personal mementos, photos and flowers to the ofrenda through Nov. 2. The fest also includes a Nov. 1 screening of “Coco” at the Harris Theater.

Visual Art
What would Downtown have looked like if Frank Lloyd Wright had gotten his mitts on it? The Pittsburgh Cultural Trust exhibit “Frank Lloyd Wright’s Southwestern Pennsylvania: The Pittsburgh Projects” spotlights new animated videos and models of unrealized residential, commercial and civic projects from the 1930s through the ’50s, including a monumental vision for the Point. The show at Downtown’s 820 Gallery, a collaboration with the Westmoreland Museum of American Art and Fallingwater, opens Fri., Oct. 24.

Theater
Pitt Stages presents the Pittsburgh premiere of acclaimed playwright Kate Hamill’s “Ms. Holmes and Ms. Watson Apt. 2B.” Hamill is known for her stage adaptations of Jane Austen novels like “Emma,” but this one’s an irreverent dark comedy that brings Holmes and Watson into the post-COVID era as somewhat dysfunctional partners in crime-solving. The show’s at Oakland’s Rauh Studio Theatre from Fri., Oct 24, through Nov. 2.

Festival
Few Pittsburgh neighborhoods do up Halloween with the verve of Allentown. The hilltop community whose retail sector cultivates a spooky edge year-round has a full day of seasonal and Hallow’s Eve events on Sat., Oct. 25. Daytime attractions include the family-friendly All Saints, Ain’ts and Souls Festival and the Trunk or Treat party. Evening Hilltop Halloween activities include everything from Halloween tats, movie screenings, Scare-aoke and pumpkin-carving to a costume contest and live music at a variety of venues, all on and around Warrington Avenue.

Visual Art
With its performing arts venues and some galleries, Carnegie is a hidden gem on the local arts scene. This week, emerging artist Justin Scott gets his first solo exhibit at Carnegie’s Double Dog Studios. “Justin Scott. A Start” features paintings from the past four years of his practice, many of them expressionistic portraits done on skateboards. The show opens with a reception Sat., Oct. 25, and runs through Nov. 15.
