TV Article Listen to Amy Winehouse's unreleased Nas duet 'Like Smoke' By Grady Smith Published on November 3, 2011 05:36PM EDT Photo: Mischa Richter Amy Winhouse's upcoming posthumous album Lioness: Hidden Treasures won't be released until December 5, but today, two tracks from the eagerly anticipated collection hit the net. One is a reggae-ish cover of Ruby & The Romantics' "Our Day Will Come." The other (below) is an original neo-jazz collaboration with rapper Nas called "Like Smoke." For whatever reason, the track, which was recorded in 2008 with Winhouse's longtime producer Salaam Remi, never got released — perhaps because it does feel as though a second Winehouse verse is missing. Still, it does serve as a sobering reminder of her irresistible signature sound. Listen to the song over at Missinfo.tv, as YouTube versions are quickly getting flagged and removed. What do you think? Are you excited to hear more from Winehouse when Lioness arrives next month?
