There’s plenty to do both inside and out on this Earth Day weekend. Here’s some of what we recommend:

Fri 4/21: Chicago sound artist Olivia Block premieres a new site-specific work at Rockefeller Chapel (5850S. Woodlawn) tonight. Peter Margasak writes, “She paid five visits to the venue and worked with house organist Thomas Weisflog to get a handle on the instrument and the complex acoustic properties of the space, and she’ll share her research in a piece called 132 Ranks, named for the groupings of pipes in the cathedral.” 8 PM

4/21-4/23: C2E2, the weekend celebration of comics, television, cosplay, and more at McCormick Place (2301 S. Lake Shore), is for more than just comic-book geeks. The massive convention features panels, screenings, exhibitors, and plenty of famous faces including Vincent D’Onofrio, Clare Kramer, Stan Lee, and the kids from Stranger Things. Fri-Sat 10 AM-9 PM, Sun 10 AM-5 PM
