If you were impressed with Meryl Streep’s guitar-playing prowess in her latest film, Ricki and the Flash, you may well have to give a small note of thanks to rock legend Neil Young. We’ve already heard about how Streep tirelessly trained for her role in the film—until her fingers literally bled!—but in this video clip courtesy of the Jacob Burns Film Center, the 69-year-old Young gives the 66-year-old Streep an impromptu tutorial on reverb, distortion, and all the other ways you can make your guitar work for you, all by way of preparing for her role as aging rock-and-roll frontwoman Ricki Rendazzo in the Jonathan Demme film.

Sporting an impeccable patterned wrap scarf and joined at times by an adorable poodle (hers? Neil’s? the music-studio equivalent of a bodega cat?), Streep takes a couple echoey strums off the guitar and takes a good bit of delight in how badass it sounds. “Oh man, that’s fun,” says the three-time Oscar winner, delivering a typically note-perfect performance of how your mom would sound if Neil Young put a guitar in her hands. “That’s because I turned everything all the way up,“ Young explains, “and that's what I want you to always do.”

With raucous barroom renditions of “American Girl,” “Drift Away,” and a version of Pink’s “Get the Party Started” that I doubt Neil Young himself has ever attempted, it’s fair to say that Streep took his advice to heart. No word yet on whether Streep returned the favor, but we'll know if Young sports a flawless Polish accent on his next album.
