Mix-tape movies

Sound Unseen Festival turns 10 this year. In celebration, the music-themed film festival has put together an eclectic, stimulating lineup. The big grab this year is Sunday's closing film, director Ondi Timoner's documentary "We Live in Public," about Josh Harris, "the greatest Internet pioneer you've never heard of." It won the Grand Jury prize at Sundance this year, making Timoner the only director to win the award twice. The other was for "Dig!," screening Saturday.

A fascinating nonfiction look into the world of a man, going only by his last name (the titular Trimpin), who turns art into music, and vice versa. I loved the sequences with the Kronos Quartet as they prepare for a totally bizarre performance of some of his creations. (7 p.m., Trylon) ★★★

A well made and exhaustive jazz documentary. Interviews with more than 75 musicians makes for a lot of talking heads and more telling than showing, but those who love the likes of Thelonious Monk, John Coltrane and Charlie Parker will feel right at home. (7:15 p.m., Oak Street) ★★★

Cory McAbee's oddball sci-fi/western hybrid thing went way over my head, but it doesn't deserve to be dismissed, thanks to McAbee's goofy, fun songs and his earnest approach to the material. If you like cultish, experimental film, this may be up your alley. (9:30 p.m., Oak Street) ★★

Also tonight: International shorts (9 p.m., Trylon). Michael Jackson tribute (11:15 p.m., Oak Street).

Nine-year-old Priscilla Diaz starts as the youngest rapper on the scene. She's talented, but it's sad to think of her inevitable future as she tries to support her father and older sister by getting a record deal. The novelty wears off, as does most of your sympathy for P-Star's father as he spends money faster than she earns it. (5 p.m., Trylon) ★★ 1/2

This breezy film is a musical that doesn't feel like a traditional musical. Shot on wonderfully grainy, handheld 16 mm in the style of the French New Wave, it has some rough spots, but its charms smooth it out. The fun is seeing where director Damien Chazelle's camera will go next. He's like an ADHD-addled sixth-grader and the camera is his dog, pulling him this way and that, looking for happy accidents and compelling story lines. (6:45 p.m., Trylon) ★★★

(Midnight, Oak Street) ★★

This documentary about a black metal scene in Oslo left me wanting more. I never got a good understanding of the music. Contains two scenes of horrifically (and purportedly real) violent suicides.

Also Saturday: "Bound for Glory," Woody Guthrie bio-pic starring David Carradine (2 p.m., Trylon). "The American Astronaut," 2001 lo-fi sci-fi feature from "Stingray Sam" director Cory McAbee (4:30 p.m., Oak Street). Local shorts (7 p.m., Oak Street). "All Tomorrow's Parties," DIY doc about the cult music fest (8:45 p.m., Trylon).

Subjects with vision, ambition, talent and seriously self-destructive patterns fascinate Ondi Timoner, one of the most exciting documentarians today. Her latest is Josh Harris, who in the 1990s created Pseudo.com, the first Internet television network, then sold it for millions. After that ... well, no fair ruining where the story goes. It's engaging as hell, and especially recommended to those fascinated by how the Web affects us and where it's heading. (7:30 p.m., Cedar Cultural Center) ★★★★

The floors of the Cedar may need mopping after this one. It had me crying like a baby. Director Jim Granato tells the story of Rogue Wave drummer Pat Spurgeon as he tours despite a failed kidney. He pursues his passion, consequences be damned, and you'll root for him the whole way. (5 p.m., Cedar Cultural Center) ★★★ 1/2

If you already like gypsy-punk band Gogol Bordello, this is for you. You'll get some good insights. Otherwise, this is fairly standard music doc territory, even if frontman Eugene Hutz is an original, engaging and fun personality. (3 p.m., Cedar Cultural Center) ★★ 1/2
