When you head to your favorite record store on April 23rd, look for one of the 1,100 copies of Live at the Record Store, a compilation album meant as a companion for Record Store Day: The Most Improbable Comeback of the 21st Century by Larry Jaffee. The album will feature in-store performances by Paul McCartney, Metallica, Frightened Rabbit, Mudhoney, and of course, Pearl Jam.
If you score one, pair it with a deluxe 12" hardback edition of the book available only at record stores and indie book stores, and if you don't score the record, still get a copy of the book.
Happy hunting!
