Looking for a complex, introspective album? Look elsewhere, because Black Diamond practically explodes out of your speakers. Powered by the high-octane beats and vibrant spirit of Angolan kuduro, tracks like “YAH!,” “Sound of Kuduro,” and “Kalemba (Wegue-Wegue)” have been making the rounds for quite some time but still sound totally fresh. This is urgent, hard-edged music, and BSS actually spends much of their debut album moving beyond their kuduro roots, with “Aqui Para Vocês” featuring Brazilian baile funk songstress Deize Tigrona and “IC19” sounding a long-lost rave anthem. For all the hype about the emerging electronic sounds of the third world, Black Diamond transcends the blog noise and solidifies BSS as one of today’s most exciting dance acts.
