London’s Airhead bounces back after the luxurious ‘Wait’ single with a new double-sided one for R&S. ‘Pyramid Lake’ is a chaotic spinning wheel of oscillating manipulations, ghostly vocal wailings and pressurised percussion. It’s as plush and lavish as it is nauseating and intoxicated. B-side ‘Black Ink’ meanwhile is a bubbling, percussive roller that sucks you in with uplifting, haunted chords.
