The Terrence Malick-directed, Austin-filmed drama “Song to Song” will open the South by Southwest Film Festival on Friday with its world premiere at the Paramount Theatre.

The movie is described as a “modern love story set against the Austin, Texas music scene” and stars Ryan Gosling, Rooney Mara, Michael Fassbender and Natalie Portman.

But — because it was filmed in part during several Austin music festivals — there is no shortage of musical artists who made the final cut of the film. Online magazine Pitchfork ran down what cameos you should look for as SXSW gets underway:

Lykke Li plays Ryan Gosling’s ex-lover and the two of them perform Bob Marley and the Wailers’ “It Hurts to Be Alone” together, in a version produced by Nigel Godrich. The Black Lips play Rooney Mara’s band, and, yes, that scene where Val Kilmer chainsaws an amp while Mara plays guitar on stage with them at Fun Fun Fun Fest is in the movie. (Austinite) Dana Falconberry plays Rooney Mara’s sister. (Austin band) Black Joe Lewis & the Honeybears play a band getting their record produced by Michael Fassbender.

Other musical artists in the film include:

Legends Iggy Pop, Patti Smith and former Sex Pistol John LydonCalifornia’s Red Hot Chili PeppersAlan Palomo, whose band Neon Indian is from DentonBounce queen Big Freedia and rapper Spank Rock

Not surprising for a Malick film, several big names were filmed, but didn’t make the movie. Pitchfork mentions Arcade Fire, Fleet Foxes and Iron & Wine as among those to hit the cutting room floor.
