What, exactly, is the “wilderness” to which U.K. house label Buzzin’ Fly refers in the title of this new anniversary compilation? The wilderness of wild success in a shrinking milieu? No matter. Over two “retrospective” CDs, Wilderness proves that Buzzin’ Fly has managed to churn out some of the finest club-house (Justin Martin’s breezy “Sad Piano”) and gastro-pub soundtracks (Jimpster’s downtempo masterpiece “Square Up”) of the 21st century. The third CD is a look at things to come–essentially Discs One and Two combined into a kind of über-house exemplified by Stimming’s Mozart-meets-Villalobos “Kleine Nachtmusik.” It’s evidence that Buzzin’ Fly’s mission of pushing dance music will continue to bear fruit for half-decades to come.
