In New York, heat runs on steam. Although radiators are notorious for their banging, clanging and shrieking, they do get the job done.

Henry Alford is actually a fan of those steam-powered screeches — to him, they’re music: “Sometimes when I hear my radiator, I think: Renata Tebaldi.”

Alford and producer Pejk Malinovski were so taken with the noise, they decided to compose an entire symphony out of the radiator sounds they'd collected.

Stay warm.
