A few years ago, the great stand-up comic Tig Notaro was diagnosed with breast cancer. And in an instantly legendary stand-up set at Largo in L.A., she processed that diagnosis, as well as the death of her mother, an infection that almost killed her, and a bad breakup in front of an audience that couldn’t believe what it was seeing. The new Netflix documentary Tig follows the story of what’s been going on in Notaro’s life after that famous set, which Louis C.K. released as a comedy album. And Sharon Van Etten, a fan of Notaro, wrote a lovely new song called “Words” specifically for the documentary’s end credits. It’s a haunted, bittersweet number, with Etten crooning about the power of words over a warm synthetic backbeat. Listen to it at Vulture and watch the Tig trailer below.

Tig will be available on Netflix on Friday.
