The minds behind the Org: Asylum show tonight at Oberon promised more artists were being added to the lineup, and they weren’t crazy. One very notable addition: Amanda Palmer, last seen at Oberon during her 2010 run of “Cabaret,” has confirmed not only that she’ll appear at the Asylum show, but that she’ll be reviving a piece literally not seen for years.

“I’m going to revive one my vintage Pan 9 performance art pieces,” she tweeted this week, referring to the Allston underground performance space that burned down Dec. 29, 2006, after years hosting epic, semi-public parties with art of all sorts.

Palmer, a one-time resident of the famed Cloud Club in the South End, has done plenty on this side of the river as well. Her Dresden Dolls, the “Brechtian punk cabaret” band, performed all over Cambridge, including regular shows at the Onion Cellar at Oberon (known at the time as Zero Arrow), and she famously worked as one of Harvard Square’s “living statues” for dollar bills before taking off to acclaim in the Dolls and as half of conjoined-twin performers Evelyn Evelyn.

The “Org” event tonight explores “issues of insanity and sanctuary,” according to organizer Singer Mali, with the same variety of performance as what visitors to Pan 9 saw. The schedule includes a short film shot on location at a local abandoned state mental hospital, a body-painting storyteller sharing tales of art-making and suicidal ideation, an interpretation of Vaslav Nijinsky choreography done in the style of butoh — the frequently grotesque avant-garde dance originated in Japan — and, of course, performance art from Palmer.

“Org: Asylum” is at 8 p.m. Sept. 30 at Oberon, 2 Arrow St., Harvard Square. Doors open at 7:30 p.m., with seats going for $20 and admission for those who plan to stand costing $15. The show is 18-plus. Performers include Jaggery, Hello Dust (Carla Kihlstedt and Matthias Bossi), Jennifer Hicks, Ginger Ibex, Sarah Josselyn, Karen Montanaro, Bryan Papciak, Michael Pope and UnAmerika’s Sweetheart Karin Webb.
