Surprised that
Machina II/The Friends & Enemies of Modern Music by The Smashing Pumpkins hasn't already been posted!
I recently found this legal, free, album by the Pumpkins. I did some research, thinking a whole free album of theirs was too good to be true. I found out Corgan had planned
Machina to be a double album, but was denied by the record company after the failure of
Adore. So, instead of giving up, the Pumpkins still recorded the extra material, but only 25 special records were produced, with specific instructions to "Distribute online freely". Enjoy over 90 minutes of great music!
