In response to a question left in the Comments section by John, here's where the series currently stands regarding upcoming titles:
Aretha Franklin's Amazing Grace - just published
Portishead's Dummy - just published
Talking Heads' Fear of Music by Jonathan Lethem - this will publish in March/April 2012
Liz Phair's Exile in Guyville by Gina Arnold - we don't yet quite have the final manuscript, but fully expect to publish this in May/June 2012
Weezer's Pinkerton - this project has been cancelled
Wu Tang Clan's Enter the Wu Tang - this project has been cancelled
Tori Amos' Boys for Pele - this project has been cancelled
Funkadelic's Maggot Brain - this project is still alive, and partially written, but I wouldn't hold your breath...
Outkast's Aquemini - this project has been cancelled
The Clash's London Calling - this book is deeply, profoundly cursed. If you pre-ordered it in 2004 when it was first announced, I can only apologise...
Lucinda Williams' Self-Titled LP - 90% written, but cannot be confident of a publication date
Kate Bush's The Dreaming - unlikely this will ever happen, but not yet officially cancelled
And that's it, for the moment! Apologies for the messiness and frustration caused by late and cancelled titles, but that's part of the fabric of the series. It's more difficult than it seems, to write 30,000 original and insightful words about a favourite record...
