Kim Gordon doesn't pull any punches in her upcoming memoir, Girl in a Band, and, in an excerpt of the audiobook edition, she makes it clear that Sonic Youth's last show in 2011 wasn't the feel-good event it might have seemed to be.

Billboard premiered the first few pages of the book—read by Gordon in audiobook format—on the podcast the Alt in Our Stars; the memoir begins with Sonic Youth preparing to take the stage together for the last time at a festival in Brazil. Gordon describes the actions of ex-husband and former bandmate, Thurston Moore, at the show as disingenuous and accuses him of "rock star showboating":

Thurston double-slapped our bass guitarist Mark Ibold on the shoulder and looked across the stage, followed by Lee Ranaldo our guitarist and Steve Shelley our drummer. I found that gesture so phoney, so childish, and such a fantasy. Thurston has many acquaintances but with the few male friends he had, he never spoke of anything personal. He's never been the shoulder slapping type. It was a gesture that called out, 'I'm back. I'm free. I'm solo.'"

Of course, this isn't the first potentially controversial tidbit to emerge from the book. Gordon also calls Smashing Pumpkins frontman Billy Corgan a "crybaby" and trashed Lana Del Rey because she "doesn't even know what feminism is."

Gordon also shared a new song called "Close Your Eyes," which she wrote for artist Nick Mauss' ballet last fall at London's Frieze Art Fair. Listen to the five-minute book excerpt below starting around the 4:00 mark. The song is played near the end of the show.
