Norwegian producer Todd Terje’s “Spiral” comes tumbling down like forty years of disco that had been packed tight behind an an attic door suddenly being released onto your head. “Spiral” unwinds to almost ten and a half minutes, and is perfect for soundtracking a nighttime flight of fancy across the frozen lake out behind your cabin which is also the cabin from the Wham! video for “Last Christmas”. Synths bleat across the totem tracks of artificial drums as digital finger snaps pop sharp and swinging between variously qualifiable arpeggios. Truly: this is not your parents’ disco.
