Book excerpt: An art form combining the skills of a DJ with the intimacy of a letter, a good mixtape was the ultimate audio valentine. Today, when the iPod and playlists reign supreme, the cassette has been rendered obsolete, and the art of crafting these sonic calling cards has been relegated to back-of-the-closet, thirty-something nostalgia. Now, thanks to Jason Bitner, we can relive our lost youth and lost loves. In Cassette from My Ex, sixty noted writers and musicians wax poetic about their own experiences with these charming artifacts and the relationships that inspired them. Contributors include: Maxim editor Joe Levy Author Rick Moody Former Rolling Stone writer and MTV2 veejay Jancee Dunn The Magnetic Fields' Claudia Gonson Stories range from the irreverently sweet, such as the doomed love affair between a Deadhead and a Goth, to the touching, such as the heartbreaking discovery of a former love passing away. Everyone will find a story or a song to relate to. Just hit play.
