Recently was documenting all the CDs I own and looking at the liner notes for Black Foliage I notice they requested people send in tapes describing dreams they had and environmental sounds for their next project. As far as I know this was not used for anything as immediately after this the band had a falling out due to conflicting ideas of wanting to keep going or take a break. Info on this 1998-2000 era album is fairly scarce. In 2009 they'd reform and start work on a third album up until 2012 where main member Bill Doss would die leaving the album on indefinite pause. It's unknown if this Post-Reunion material was based on anything from before they broke up, and both albums are very scarce when it comes to content, with the only thing we currently have being the single release in 2011.
I didn't listen to any of the Circulatory System albums or The Sunshine Fix albums after this but I did skim them and couldn't find anything.
