A posthumous collaboration between Amy Winehouse and legendary Queens rapper Nas has surfaced online.

Taken from forthcoming Winehouse retrospective Lioness: Hidden Treasures, the music comes courtesy of a 2008 retro-soul production from Salaam Remi, with Nas toasting Camden and Funky Buddha (and, er, using the phrase “colder than penguin poo”) over Winehouse’s backing [via MissInfo].
