I have just uploaded a whole bunch of mostly prog surround sound items for sale on discogs.com. I'm selling these items from the personal collection of a NEARfest attendee and long time PE member, Keith Ling (aka Jubal), who passed away recently. About 2/3 of the proceeds will go to his widow Kelly Ling. Please visit discogs.com and search "laduca" as seller name, or click the link below. I will be uploading another batch of items from Keith's collection tomorrow, as well.
