Tegan from Tegan and Sara

Thursday night promises to be full of rare moments for Tegan Quin, half of sister duo Tegan & Sara. She'll be performing a song that she wrote to accompany the audiobook of Augusten Burroughs' A Wolf at the Table for the very first -- and possibly last -- time in front of a live audience, and she'll be appearing for only the third time without her sister, Sara.

It's all part of SPIN.com's first-ever Liner Notes event, a benefit for NYC AIDS charity Housing Works featuring performances and readings by Tegan, Burroughs, Circa Survive's Colin Frangicetto, Elizabeth Seward, and Anberlin's Stephen Christian. The sold-out event is set for Thursday, Sept. 4, at 8 P.M. at the Housing Works Bookstore Café in New York City.

In the video interview below, with SPIN.com Book Club curator Emily Zemler, Tegan talks about how the collaboration with Burroughs came together and what it's like to play without her sister.

Be sure to check back to SPIN.com on Friday for photos and video from the event!
