Groomed for mainstream success, Big Brovaz?an eight-strong London collective?rival their transatlantic contemporaries for marketing ambition and bling-bling blarney. The concept is shameless, too, matching up two producers, three male rappers and three female singers to create a lucrative hybrid of OutKast and Destiny’s Child. Sadly, the music doesn’t measure up. While the women sing decently, the rapping is unexceptional: it would have helped had they understood there was more to OutKast than flash and clowning. There’s little here to give their US idols sleepless nights.
