For cackling good times with a celebrated figure of the dark arts, Sebastiani Theatre is hosting the 40th year of Witchie Poo’s Spectacular Halloween Extravaganza. Pervasive, kid-friendly, Transylvania themed decor that fills the theater can be explored while the Sebastiani Theatre House Band opens with seasonal music. The stage performance features the one and only Diana Rhoten as Witchie Poo, who travels to Transylvania for a musical romp—if her nemesis, Captain Long John Silver, doesn’t thwart the good time. Doors 12:30pm, show 1pm, Saturday and Sunday, Oct. 28 and 29. Tickets are $15 for adults, and $12 for children (12 & under) and seniors (62 & better). Sebastiani Theatre, 476 First St. East, Sonoma.
The adult side of Halloween has as much to do with the holiday’s lasting appeal as it does with the candy. As the name implies, the Mischief & Mayhem Halloween Party at The Saint in St. Helena gets that some things as sweet as candy might be just as dangerous. “Surrender to the electrifying beats of DJ Kirill” and “bewitching cocktails” for a night of masquerade ballin’, say promoters. Come in costume to rule the room. 9pm–1am, Saturday, Oct. 28. The Saint, 1351 Main St., St. Helena. Advance tickets required, starting at $55/person. Reserved VIP tables available. thesaintnapavalley.com/event-tickets. 21+.
Where could be a better venue to invoke the restless strangeness of fall that Halloween celebrates than the Lost Church? Performers Bright Dark Dawn, Maya McNeil and Benjamin Pearl bring their own mystical voices to songs about this time of transformations, the interplay of light and the night, and tales of “creature-kin from other ages,” according to publicity. Ghost Songs, doors at 7:30pm, show at 8:15pm, Sunday, Oct. 29. The Lost Church, 427 Mendocino Ave., Santa Rosa. $20. All ages.
Halloween is a tradition that affirms life by celebrating the specter of death. The Marine Mammal Center of Sausalito is offering a unique way to engage in this dichotomy through a livestream introduction to the work of the center’s pathologists. These experts do the detective work of learning how and why individual animals died—called necropsy—to contribute to the scientific understanding of these ocean species. Dr. Maggie Martinez will answer questions along with Adam Ratner, director of conservation engagement. Viewer discretion advised: images of medical work on deceased animals. Learning Through Death. 12–1pm, Thursday, Oct. 26. Livestream. Free. Register at eventbrite.com/e/virtual-halloween-event-learning-through-death-tickets-731456545217.
