Demos leaked on the internet, some guy found it and uploaded to the internet. This is actually like a present from Karen O to the guitarist of "TV on the Radio". This never intended to release to the public.
I Already listen to it and found that it is not so good, but because i'm the fans of "Yeah Yeah Yeahs" i find it interesting. It's like a B-side album that never gonna released but leaked. Theres no formal track listing for this disc, but Karen O has said that track 6 is called "Pumpkin" and track 7 is called "Snakes and Worms". Here's the link KO at Home
