Great day for Ghostface: first the “I ain’t shoot nobody in like…since the early 90’s, man” quote in Hip-Hop Connection, by way of explaining that his next record will be primarily r&b, and then “Harbor Masters,” a super ’90s-sounding collaboration with AZ (!) and Inspectah Deck, apparently destined for Wu-Tang: Chamber Music, on which various Wu dudes will rhyme over music performed by Brooklyn’s the Revelations. Whose dusty, drawling beats are maybe the most convincing corroboration to date of the Wu’s aggrieved and very public frustration with RZA’s beats on 2007’s 8 Diagrams: It really is different to hear guys like Ghost and Deck over stuff they’re actually comfortable with. Jennifer Convertibles (and matching nightstands), cold fresh-squeezed OJ, Mohammed Atta, and most fluent verse from Inspectah Deck in years all feature heavily. In the last century, songs like this one basically grew on trees, but in 2009, “Harbor Masters” is about as good as it gets from rap’s over 30 crowd.
