So, we have 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.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 Pitchfork 500 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, here's Jess Harvell on Sonic Youth's "Teen Age Riot", with a stream (good for one free play every 24 hours, via Lala) below the text.
