“… this is “journey music“ in a literal sense. Schlienz and his partner Hanno Braun actually recorded the piece in the loneliness of Iceland’s high plateaus, nearby active volcanos and in the midst of stony deserts – hence the title…”
It plays like archive telemetry from a 1970s expedition to another world.
It’s also available on cassette, but I would have paid real money for a CD release.
