Here is a sampling of the week’s events and how to tune in (all times are Eastern). Note that events are subject to change after publication.
Consider the outsize impact of Richard Wagner during a digital evening presented by Powerhouse Arena in Brooklyn and the Wagner Society of New York. In his new book, “Wagnerism: Art and Politics in the Shadow of Music,” Alex Ross, the music critic for The New Yorker, looks at how the 19th-century German composer’s oeuvre influenced Paul Cézanne, Luis Buñuel, feminists, gay-rights pioneers and, notoriously, Hitler. Mr. Ross chats with A.O. Scott, a critic at large for The New York Times.
When 7 p.m.
Hold a virtual magnifying glass over three large-scale abstract canvases by Mark Bradford, a Los Angeles-based artist. He created his vibrant but haunting “Quarantine Paintings” — mounted by Hauser & Wirth — while abiding by Los Angeles’s stay-at-home order. “I’m adjusting to life on Mars,” Mr. Bradford told The Times in a recent interview.
To say the United States is in the middle of a complicated moment is an understatement: The global pandemic rages on, the nation struggles with racial justice, and a consequential presidential election looms. The New York Times book critic Parul Sehgal hosts a conversation titled “The Politics of Fiction” to grapple with this moment and the place fiction has within it. Can it help us make sense of events and better understand what lies ahead? Do fiction writers have any responsibilities toward current events? Joining Ms. Sehgal is the Pulitzer Prize-winning writer Ayad Akhtar, and the novelists Marlon James and Rachel Kushner.
When 4:30 p.m.
Learn all about eggplants with the sisters Danielle Cook, a cooking instructor and nutritionist, and Adrienne Cook, a food writer. A little-known fact about the plant: Its dark purple skin contains high amounts of nasunin, a powerful antioxidant. In this recorded segment produced by the United States Botanic Garden, the sisters provide cooking and gardening tips for the produce as well as ways to keep it growing in your garden even as the temperature starts to drop.
When After 12 p.m.
Go behind the scenes of Heartbeat Opera, a Manhattan-based company that completely reimagines well-known works. As part of its weeklong Secret Sauce series, the American classical singer Julia Bullock explains how Heartbeat’s productions of “Kafka-Fragments,” “Fidelio” and “Lucia di Lammermoor” came together, and chats about the future of opera. Tickets are $30 per device.
When 2 p.m.
Join Rabbi Daniel Brenner for the first of a series of High Holy Day celebrations streamed live from New York City’s Brooklyn Bowl. Jordan McLean, a composer and co-founder of the Brooklyn-based Afrobeat band Antibalas, co-hosts the High Holidays 2020 series. The event is free.
When 7:30 p.m.
Practice the different parts of a Sevillana dance, a Spanish folk style, courtesy of Pasión y Arte, an all-female flamenco dance company based in Philadelphia, and the city’s annual Fringe Festival. Follow the lessons from Elba Hevia y Vaca, PyA’s artistic director, uploaded weekly to the company’s website, where you can also submit footage of your moves. It could end up featured at a virtual gathering for participants at the beginning of October.
When Through Oct. 4

Find out why virtual reality seems so real with an online visit to the nonprofit Virtual Science Center, based in Silicon Valley. Click through optical and auditory illusions (remember “yanny or laurel”?); try some of the guided activities, such as making a stereoscope to show how your eyes and brain work together; or watch conversations with people who use V.R. on the job, including Todd Chang, an emergency physician at Children’s Hospital Los Angeles. He relies on virtual simulation to train medical staff.
