This one has been buzzing around as an ID for a few months, first surfacing at Solarstone's Open To Close (in Dolby Atmos) at Ministry of Sound back in January. It is a deep and dark sultry affair, which moves at a sedate 126pm. The backstory; Gordey, having previously released the majestic Radiance on Pure Prog back in 2016, sent Opacity as a demo to Solarstone, who saw within the demo a glimmer of something truly glorious, if only the track could be stripped down and reassembled with a clear intention; maximum impact in a big, dark fog-filled room - lit only by strobes. The impact of this track on the floor can't be overstated, and the key-change twist which hits at 6 minutes in is a work of art.
