An apartment steeped in musical history at Tribeca’s American Thread Building is on the market for $7 million. The listing was first reported by 6sqft.

Part of the sprawling 3,800-square-foot unit, at 260 Broadway, was once the Duplex Sound Studio, and owned by Brazilian composer and Grammy-winning artist Eumir Deodato, who is the grandfather of Hailey Baldwin (now Bieber).

Back in the day, this is where Frank Sinatra, Aretha Franklin and Tony Bennett recorded music.

The exquisite loft, decked out by Interior Marketing Group, features details like arched windows, Roman-style columns and high ceilings.

The listing broker is Leonard Steinberg, of Compass.
