I think they made few releases in the 80`s and then they abandoned the project. Then resurrected the project back in 2004 and have been pretty active since releasing both older works and new stuff. I really enjoy some of their work, especially the ones released through Helen Scarsdale Agency label (lots of other great stuff in there as well like Sigtryggur Berg Sigmarsson, Loren Chasse & Michael Northam, Jim Haynes etc.)
