When it comes to beats and rhymes, Canadian producer Marco Polo and Brooklyn MC Torae don"t play, just check the r‚sum‚. On his 2007 critically acclaimed album Port Authority, Polo recruited a who"s who of MC"s like Kool G Rap and Kardinal Offishall to ride over his hard-hitting instrumentals. Torae, on the other hand, has certified his rep as one of the game"s illest lyricists in a similar fashion, with remarkable wordplay on his highly touted 2008 street album Daily Conversation. So, in the spirit of great Hip Hop duos, the producer and the MC release their 2009 collaborative album Double Barrel.
