Sunday’s 40th annual Halloween concert at Hill Auditorium -- which combines the Campus Symphony Orchestra with the Campus Philharmonia Orchestra -- will mark conductor Kenneth Kiesler’s 23rd time on the podium while in costume. (What he’ll be dressed in this year is under wraps.)

But what you might not know is that he and the student musicians get one chance each year to raid the theater department’s costumes.

“They have a huge warehouse,” said Kiesler. “You could get just about anything you want.”

Reading a long list of sponsors doesn’t usually prompt a standing ovation; but because celebrated New York Times op-ed columnist Charles M. Blow couldn’t hear, while backstage at Rackham Auditorium on Friday evening, what was being said while waiting to make his entrance, he gamely emerged before his official introduction had even gotten underway.

Not that the adoring, full-capacity crowd minded the miscue in the least. Presenting the keynote speech of a Humility in the Age of Self-Promotion Colloquium at U-M, Blow spoke for 40 minutes on the topic of Trump, arrogance, and democracy, and answered audience questions for an additional half hour.

One article about the popular, fiercely beloved Welcome to Night Vale podcast begins with the line, “Unless you’ve been living under a rock, you’ve heard of” the show.

But until I’d received a copy of the novel It Devours! written by the podcast's creators, Joseph Fink and Jeffrey Cranor, and researched Night Vale in preparation for a recent phone interview with Cranor, I’d been one such under-the-rock dweller.

Yet because the podcast could be described as the David Lynch version of A Prairie Home Companion -- focusing on a fictional desert town in the American Southwest, where all conspiracy theories are true -- I asked Cranor if any of Night Vale’s residents also live under rocks.

“No, but one of the characters is a rock -- the dean of the Night Vale Community College, Sarah Sultan,” said Cranor without missing a beat, referring to a character who communicates via telepathy.

Well, then. At least I might have some company.

Joseph Fink and Jeffrey Cranor will be with artist and illustrator Jessica Hayworth at U-M's Lydia Mendelssohn Theatre on October 23 at 7 pm, courtesy of Literati Bookstore. The three will be interviewed by Detroit writer, actor, comedienne, and The Moth Storyslam Ann Arbor host Satori Shakoor, followed by an audience Q&A and signing.

Cranor answered questions for Pulp about Welcome to Night Vale and It Devours!.

I once spent a summer reading just about everything Albert Camus wrote. Not exactly beach reading, I know -- I jokingly referred to it as “my crazy summer” -- but I’d been hired to write the preface of a book about the French writer’s work, so I dove in.

I hadn’t counted Camus' seldom-produced 1948 play L’Etat de siège (State of Siege) among my favorites of his writings, but I was intrigued that Théâtre de la Ville was staging it. Having seen previous Théâtre de la Ville productions courtesy of University Musical Society (UMS), including Ionesco’s Rhinoceros in 2012 and Pirandello’s Six Characters in Search of an Author in 2014, I was hopeful the Parisian company's past lavish renderings of absurdist classics would nonetheless find a way make Siege sing.

And yes, Theatre de la Ville’s take on Siege at the Power Center on Friday and Saturday looked slick and offered some truly inspired moments of stagecraft, but Camus’ heavy-handed political allegory still ended up feeling pretty leaden.

On Thursday evening, world-renowned sculptor Christo, 82, told a huge crowd -- packed into the Michigan Theater to see him -- what might be the best, most succinct courtship story of all time.

Of his longtime partnership with Jeanne-Claude, with whom he collaborated on his massive art installations (and who died in 2009), Christo said, with a shrug, “I was very young, we make love, and we like each other. That’s all.” Moments later, he added, “She was very pretty.”

But Christo -- dressed in dark slacks, a collared white shirt, and a big-pocketed beige jacket that hung off his lean frame -- initially kicked off his Penny Stamps Speaker Series lecture with a few parameters: “I will answer all questions, but I will not talk about politics, religion, and certainly not about other artists. I talk about myself, my work, and anything that I can tell you about my work.”

When you put the wrong date in your calendar for an interview with Jen Mann, the blogger/author behind People I Want to Punch in the Throat, you kind of fear that you’ll be added to the list.

But Mann -- who will be coming to the downtown library for a moms’ night out event on Wednesday, October 11 at 7 pm, as part of a book tour to promote her latest humorous essay collection, Working with People I Want to Punch in the Throat -- couldn’t have been more understanding, despite her famously feisty, tell-it-like-it-is persona.

Not so long ago -- last year, to be precise -- in a venue that’s close, close by, the Ann Arbor Symphony Orchestra (A2SO) played two sold-out concerts featuring John Williams’ music from the Harry Potter films. The audience response was so enthusiastic that A2SO immediately started making plans to perform two concerts featuring Star Wars music, and those concerts will happen Saturday night and Sunday afternoon (October 7-8) at the Michigan Theater.

“We were so overwhelmed (last year) ... and the audience, some of whom had never seen a live symphony concert before, told us that the music evoked powerful images for them, even though there was no visual component accompanying the music,” said A2SO conductor Arie Lipsky. “They also told us that they’d never thought that music had played such a vital role in the movies, and they thanked us for highlighting the music on its own. So many said, ‘Now we’re hooked on seeing live symphony orchestra shows,’ and we responded by investing in music from all the Star Wars movies.”

In 2015, I pronounced Into the Woods to be Encore Theatre’s strongest overall production since the Dexter company opened its doors in 2009.

Well, move over, Into the Woods. There’s a new Sondheim show in town, and when it opened on Friday night, Sweeney Todd: The Demon Barber of Fleet Street quickly established itself as the best thing yet to happen on Encore’s modest, black-box stage.

Nancy Pearl -- coming to Nicola’s Books on Wednesday, October 4 at 7 pm to talk about her new novel, George & Lizzie -- may be the only person in America who could be referred to as a “celebrity librarian.”

For she’s regularly featured on NPR, where she recommends and discusses books; and she was the model for a librarian action figure that boasts “amazing shushing action!”

But locals who’ve heard Pearl on the radio may not realize that she has deep local roots. Though she now calls Seattle home, Pearl grew up in Detroit and studied library science at the University of Michigan.

In order to play at The Ark’s nearly sold-out fall fundraiser on Sunday night, Darlingside had to skedaddle out of Kansas City after a show on Saturday night. The Boston-based quartet packed into a minivan with its sound engineer and drove through much of the night.

This hadn’t been the original plan, but the sudden appearance of a 200-mile-wide storm system meant that Darlingside's flights, scheduled several months earlier, weren’t going to happen. “So we arrived in Ann Arbor this morning, badly in need of a shower,” confessed cellist/guitarist Harris Paseltiner.
