Well there was that one song, Dark Morning Conspirators. Unreleased Crash Love song, as of yet unfinished because of some issue with the vocals. Davey says it kinda sounds like I Am Trying Very Hard to Be Here. There's also one song recorded but currently unreleased from the Blood Album sessions.
Good luck trying to get your hands on those, though. Probably sitting on Jade's iPod or on some CD-R somewhere in the members' respective houses.
Technically, Breathing Towers to Heaven was a demo. Not sure who tracked it though. May have been at Jade's house but the guitars sound too good for that. Drums are clearly overdubbed and a bit plastic sounding, which makes me think they were programmed in the box. (Love it all the same.)
