Music recorded over a single night by Sufjan Stevens, The National’s Bryce Dessner and more was recently collected for a limited-edition release called ‘One Night Stand’.

Gaspar Claus invited several artists – also including members of Porcelain Raft and The Men – to collaborate for the Brooklyn-based project in 2012.

The 11-track, 70-minute release collects elements of the performance, with The Blogoteque’s Derrick Belcham providing an accompanying film.

It was released on June 30.
