Following a quick souncloud search for Live Skull which threw up just one song (from the days before Thalia sang) I found a great set by Thalia which I was previously unaware of:
Amazing really that the song "Searchlight" hasn't been recorded for any of Thalia's better known albums. She just finished recording her new album which will be released by Thrill Jockey in March.
Thalia wrote this: ""Nature of Drones" was a homemade tour CD that we made for an Australian tour that we did. Super limited quantity , we sold the remainder through the Thrill Jockey website."
