Well, I know they are not on Lost Pieces 1 or 4. I'm not one-hundred percent sure about 2 or 3, but I don't believe they are on those either because those came out long after I had recorded this music on the radio. I listened to some samples from Desert Solitaire and Western Spaces too, but I didn't hear them there either. They really sound like Steve Roach pieces, like you said, especially that second track. This is killing me, i have been sifting through a lot of Roach's music but I haven't heard these tunes, although I have heard tunes a lot like these. If anyone reading this knows a bigtime Steve Roach fan could you have them give these tunes a listen, I would be very grateful!!
