So, we've got a new book out, The Pitchfork 500: Our Guide to the Greatest Songs from Punk to the Present, published by the Simon & Schuster imprint Fireside Books. It explores our 500 favorite songs from 1977-2006-- interspersed with sidebars on the most vital subgenres from electro to grime to riot grrrl-- to construct an alternate history of the past three decades of popular music. In the coming weeks we'll be posting streams of tracks from the book here in Forkcast and giving you a sneak peek at some of the entries. Geeks that we are, we love list-making, but we're even more interested in writing about music and discussing ideas, as we hope you'll see.A quick note on some upcoming events. In Chicago tonight at Borders Books & Music in Lincoln Park (2817 N. Clark St.), Pitchfork editor-in-chief (and Pitchfork 500 co-editor) Scott Plagenhoef and Pitchfork managing editor (and Pitchfork 500 contributing editor) Mark Richardson will read from The Pitchfork 500, followed by a Q&A session and a book signing. Tomorrow, November 14, New Yorkers can tune into WRXP-FM's "Matt Pinfield in the Mornings" at 8 a.m. Eastern for an interview with Ryan Schreiber, while Chicagoans can catch Scott on WGN at 2 p.m. Central with host John Williams. This Tuesday (11/18) here in Chicago is the official launch party at Sonotheque (1444 W. Chicago), at which we'll be spinning selected tracks from the book from 9 p.m. to 2 a.m. For a complete rundown of events, check www.thepitchfork500.com.The book is available in your local bookstore right now (Quimby's is the shop in our Chicago neighborhood). Or you can order it via Amazon, Barnes & Noble, Borders, Insound, Powells, or Simon & Schuster.And now, without further ado, here is Dominique Leone on Donna Summer's "I Feel Love", with a stream (good for one free play every 24 hours, via Lala) below the text.
