A showpiece for the remarkable capacities of what some consider the greatest synthesizer ever made: the Yamaha CS-80, which can still fetch $50,000 on the secondary market today. In Vangelis’ hands, it does serene, dreamy blues (“Blade Runner Blues”), eerie tension (“Blush Response”), heavenly glow (“Main Titles”), and more, building a remarkable sonic counterpart to the film’s dark, smoky mood. The analog synthesizer, now a nostalgic instrument, has rarely sounded so multifaceted, contemporary, and beautiful.
