The story of a young man wandering in a magical forest mixes circus arts, acrobatics, and dance in the company's distinctive kinetic style. As always, expect gorgeous costumes, stunning feats, and dazzling effects. — Michael Harrington

The found-film collector screens industrial, promotional, and educational flicks including 1967's 20 to the 3rd Power, a student work produced by the Documentary Film Laboratory of Penn's Annenberg School showing fashionable undergrads enjoying Philly; footage of Atlantic City in the 1970s; clips of Mr. Rivets, a "mechanical man" (actor Joe Earley) who was the goofy sidekick on a local TV afternoon show; and a 1976 promo for the cultish self-help program EST, featuring founding Werner Erhard (who got his start as Philly-born car salesman John Rosenberg). — M.H.

Since 2004 and its debut album Juturna (the Roman goddess of wells and springs), Doylestown's Circa Survive — powerful whiner/stream of consciousness ranter Anthony Green, jackhammering guitarist Colin Frangicetto, a prog-rock rhythm section that makes Yes sound like Selena Gomez in comparison — have made emo mean more than a haircut and teardrop. Their heartbroken emotional hardcore, tinged with sometime-silly philosophical conceits — to say nothing of Green's newly formed sensitivity as a dad and acoustic-based solo artist — and cranky rhythmic overdrive continue to make Circa Survive brilliant and even important beyond their original sphere of influence. Plus, they put out a new album this autumn, The Amulet, which you should own, so hit the merch table when Thrice, CHON and Balance and Composure are on stage. — A.D. Amorosi
6:45 p.m. Friday and Saturday, Electric Factory, 421 N. Seventh St. $34.50-$40. 215-627-1332, electricfactory.info
Masseduction, the fifth St. Vincent album, is both deadly serious and seriously fun. Annie Clark — who records as St. Vincent — downplays her guitar heroics this time in favor of M.I.A.-like provocative pop on songs such as "Pills" and "Los Ageless," foregrounding beats and quick-cuts and abrupt noises to soundtrack her apocalyptic messages. The songs veer from the personal to the political, and they're often delivered with a winking extravagance. She's dubbed this tour "Fear the Future," and it's a theatrical, multi-media affair, with a solo Clark first playing a retrospective set — expect her guitar-shredding on favorites such as "Rattlesnakes" — followed by Masseduction's savvy pop, from start to finish. — Steve Klinge
8 p.m. Tuesday, Electric Factory, 421 N. Seventh St. $41.50 advance; $44.50 day of show. 215-627-1332, electricfactory.info

Emily Haines is the front woman of Toronto rock quartet Metric, and she's also a contributing member of Canadian indie supergroup Broken Social Scene, who released Hug Of Thunder this past summer. But Haines also makes a solo album every 10 years or so, going back to Cut in Half and Also Double in 1996, Knives Don't Have Your Back in 2006, and now this year's Choir Of The Mind. The new 13-song set does rev up itself on the likes of the slow building "Fatal Gift," but mainly it's a subtle and sedate piano-centric affair, with Haines' breathy vocals paired with stately melodies. At Union Transfer, she's playing an all-ages seated show. — Dan DeLuca
8 p.m. Wednesday, Union Transfer, 1026 Spring Garden St. $26-$85. 215-232-2100, utphilly.com
If you missed Philadelphia's long-distance run last weekend, make up for lost time at a different type of marathon: a comedy marathon. For the fourth year running, the Philly Improv Theater (PHIT) gathers entertainers and comedians for a show lasting no fewer than 40 hours. The event features stand-up comedians, sketch performers, improvisers, musicians, clowns and more. If that seems like whole lot of comedy, remember that it's a whole lot less of a time commitment than preparing for a 26.2-mile endurance contest. — Thea Applebaum Licht
9 a.m. Friday to 1 a.m. Sunday, Philly Improv Theater, 2030 Sansom St. $12, or free with a receipt from a local business. 267-233-1556, phitcomedy.com.
