Carrie Brownstein is working on a memoir for Riverhead Books about her life in music, which means she’s poised to conquer yet another medium with what is destined to be a critically beloved but not quite mainstream endeavor. The book doesn’t have a title or release date yet, according to the Times. Brownstein is today’s guest on “WTF with Marc Maron,†and from her description, any book is still a ways off. “I have not written a book,†she clarifies toward the end of the episode. “I got a book deal … and got sidetracked,†she says. It sounds like that book deal morphed into this one, which will have “more of a through line†than the book she tried to write previously. The whole “WTF†episode is pretty good, especially for Sleater-Kinney fans. “Image was not a part of Sleater-Kinney or punk at that time,†Brownstein says. “Now I look back and think, Couldn’t I have shaped my eyebrows? Just a little bit?â€
