The silver lining in this year of grim isolation, chaos and despair is that 2020 has produced a huge volume of exceptionally good ambient music. RST’s year-end offering puts a locket on that silver chain. Filled with bells, befitting the holiday season, An Open Door is Thompson’s most joyful—and joyously executed—album yet. A truly wondrous listening experience created by RST’s unique electroacoustic blend. (If you like this album, also check out Telemetry—Remixed.) Favorite track: From a Language of Light.
