What is "fuckbook"

Fuckbook is an album released by indie rock band Yo La Tengo under the alias Condo Fucks in 2009. The band name comes from an inner sleeve listing fake albums and genre send-ups included in their 1997 album I Can Hear the Heart Beating as One. Guitarist Ira Kaplan and drummer Georgia Hubley are credited on this album as Kid Condo and Georgia Condo, respectively. The Matador press release for the album creates a fictional backstory for the band that hints at the truth. The album is purportedly produced by Mutt Lange, mixed by Bob Clearmountain, and mastered by Greg Calbi, but this is unconfirmed and most likely part of the gag.
