SATURDAY-SUNDAY

Warhol 25

More proof that time flies is that The Andy Warhol Museum is now celebrating its silver

anniversary.

The 25th Anniversary Gala is a black-tie dinner Saturday with Joan Jett and Matthew Morrison of “Glee.” Tickets are a little steep at $750, but there is a more affordable Late Night Dance Party featuring a set by RJD2 and Operation Sappho from 11 p.m. to 2 a.m., starting at $75.

On Sunday from 10 a.m. to 7 p.m., the 25th Anniversary Community Day features hands-on artmaking, gallery talks and activities, and performances by David T. English Puppet Co., O’Ryan the O’Mazing!, Attack Theatre, Anqwenique Wingfield and more.

Sunday is also the opening of “Andy Warhol: Revelation,” a new exhibit that examines how the artist’s devout Byzantine Catholic upbringing influenced his artistic production. All the events take place at the museum on the North Shore. Info at warhol.org.
