The popularity among the young of J.K. Rowling’s novels about the boy wizard -- and the movies based on them -- should give us all some hope for the future, given the stories’ themes of protecting the weak and innocent, tolerance for difference, and unyielding resistance to the single-minded evil and insistence on blood purity of He-Who-Must-Not-Be-Named, the young wizard’s arch-enemy. If you’re not familiar with the magical realm, this first film in the series is a good place to start. — Michael Harrington

The Rodin Museum, which had been closed for reinstallation, is open once more with a focus on The Kiss, an 1889 sculpture originally made as part of Auguste Rodin's The Gates of Hell. The reinstallation is centered on the theme of passion and embrace (take a gander at the centerpiece sculpture featuring two lovers, and you'll get why) and is open just in time for Valentine's Day. -- Molly Eichel
Open now, Rodin Museum, 2151 Benjamin Franklin Parkway. Suggested donation, 215-763-8100, rodinmuseum.org.

Nights at OId City's La Peg will get a little cooler — and more tipsy — with the debut of Pegsicle, a temporary ice bar. Pegsicle will be in place through Feb. 13, providing it doesn’t melt before then. La Peg chef-owner Peter Woolsey, whom a release calls an "amateur ice carver," will create the bar out of 16 blocks using Japanese ice chisels and chainsaws. The ice bar will be in La Peg’s Haas Biergarten, which features fire pits to keep folks from getting too cold. Pegsicle also will be open for La Peg’s Big Game Hot Chicken Pop-Up event Sunday. The outdoor bar will have drinks available, including mulled wine and alcoholic hot cocoa, and craft beer from such breweries as Sly Fox and Oskar Blues. — Nick Vadala
Through Feb. 13, La Peg, 140 N. Christopher Columbus Blvd., www.lapegbrasserie.com.
David Bryan and Joe DiPietro’s Tony Award-winning musical Memphis tells the story of a white DJ struggling to play black music in the segregationist South of the 1950s. The infectious, fun show gets a sparkling production at the Ritz Theatre, a South Jersey gem. — M.H.

The acclaimed violinist and conductor and his chamber ensemble, Kremerata Baltica — hand-picked performers from Latvia, Estonia, and Lithuania — play Mieczyslaw Weinberg’s mordant, melancholy Chamber Symphony No. 4. Also on the program: works by Arvo Part, Tchaikovsky, Mussorgsky, and Valentin Silvestrov’s Serenade for solo violin (sure to be a highlight). — M.H.

The fabled Chicago improv comedy troupe arrives with its latest gang of soon-to-be superstars for the show We’re All In This Room Together, featuring recent material, made-up-on-the-spot stuff, and classic bits originated by Tina Fey, Stephen Colbert, and Bill Murray. — M.H.

The esteemed musicologist and performer, a Philadelphia native, is an expert on traditional music of Azerbaijan. He’ll play a recital of improvisational mugham music (described as “monophonic modal music, highly microtonal, meter-free, densely ornamented, and composed of complex melodic lines”) on the kamancha (a skin-faced spike fiddle), oud (a fretless short lute), and tar (a fretted long lute) in a concert presented by the invaluable Fire Museum. — M.H.

It was (nearly) 50 years ago today Sgt. Pepper taught the band to play — and since that band was the Beatles, the world of pop music has never been the same. Conductor Michael Krajewski and crew are joined by the tribute band Classical Mystery Tour to play songs from the landmark album as well as other Fab Four hits. — M.H.
Fronted by vocalist and colyricist Katie Alice Greer, these melodic hardcore-lite Washington punks are but the newest chapter in a lineage that started with Bad Brains, Minor Threat, and Fugazi. Like Priests, all of those band had a sense of socially conscious rage that’s more pertinent than ever. Priests ups the ante, (and the volume knobs) on the politically focused Bodies and Control and Money and Power EP, recent singles such as "Pink White House" and "JJ," and the band's brand-new, full-length album (timed perfectly for the insurrection around Trump’s inauguration) Nothing Feels Natural. — A.D. Amorosi

Bluegrass legend Del McCoury still tours, but at age 77, he has scaled back. When his sons Ronnie and Rob aren’t playing with him, as they have since they were teenagers in the 1980s, they lead their own expert band, The Travelin’ McCourys. And when the patriarch isn’t looking, the McCourys stretch out a bit, veering into that intersection between traditional bluegrass and jam-band experimentalism. Their unpredictability — will they honor Bill Monroe or the Grateful Dead? — is their strength. And in any setting, their musicianship -- with Ronnie on mandolin, Rob on banjo, Alan Bartam on bass, and Jason Carter on fiddle -- is impeccable. — Steve Klinge

Over a two-decade career, veteran Brooklyn conscious rapper and political activist Talib Kweli has been a serial collaborator, from his Black Star project with Mos Def to the standout verse he dropped on “The Killing Season” on A Tribe Called Quest’s sterling 2016 comeback album. On The 7 Tour, the “Get By” emcee and sometime guest on Real Time with Bill Maher joins forces with rapper Styles P. of The Lox, teasing music from a collaborative album due this year. Don’t expect Kweli to hold his tongue when it comes to Donald Trump. K’ Valentine is also on the tour, and the local Philadelphia openers are Reef the Lost Cauze and Hardwork Movement. — Dan DeLuca

On Natural Conclusion, the follow-up to 2012’s acclaimed We Have Made A Spark, Rose Cousins strips songs to their pointed and somber essence. The Canadian singer-songwriter drafted Joe Henry to produce her fifth album, and the textures, often built around Cousins’ stately piano, build slowly within songs. She has a commanding, thoughtful voice that recalls Patty Griffin’s, especially on the dramatic “Freedom” and the bluesy “Chains,” but it’s also full of longing and tenderness on “My Friend” and “Lock and Key.” The lyrics often depict emotional turmoil, and her voice becomes the calm in “the eye of every storm,” as she sings in “Grace.” —S.K.
