When my brother bought the copy of Pinkerton that we used to listen to, it came with 3 copies of the liner notes. Lucky us.

Apparently, Pinkerton evolved out of a plan by Rivers Cuomo for a grandiose rock opera album. There's an interesting bit about it at noise to signal. Check out the song "Blast Off!" that they have posted, if you want to hear Rivers through a vocoder. I know I do. Apparently "I just threw out the love of my dreams" was one of the tracks planned for the project, entitled Songs from The Black Hole. Even though Rivers barely sings on this track (replaced by Rachel Haden, older sister of ex-decemberist Petra, sister in law to Jack Black of the D, member of weezer bassist Matt Sharp's side project, the Rentals, oooh what a twisted web), it still sounds very weezer.
