The solstice has arrived and we have entered “Evening Star weather,” in honor of the second collaborative album from pioneering English musicians Brian Eno and Robert Fripp, released in December of 1975. Fifty years on, you can hear large swaths of the ambient genre echoing through Evening Star: The cosmic calm of Steve Roach’s classic 1988 album Structures From Silence. The neo-classical predilections of Eluvium and Stars of the Lid. The billowing atmosphere of Wolfgang Voigt’s music under the name Gas. The cracked nostalgia of Fennesz’s Endless Summer. Kyle Bobby Dunn’s commitment to drones that sound like sunrise on the other side of the solar system. The fuzzed-out psychedelia of Emeralds. The dreamstate travels of Windy & Carl. And so on and so on.
