As schoolkids continue to dominate the charts another teen band might sound like the last thing you feel like hearing. But although the Sugababes name makes them sound like another slice of pop fluff, these new kids on the R'n'B block are actually much more interesting than that. They may be all of 16 years old but the debut album from London girls Keisha, Mutya and Siobhan shows a maturity and musical proficiency that many of their peers might envy. Their blend of cool, laid-back soul is distinguished by mature vocals, accomplished arrangements and oblique lyrics. Now that the Spice Girls are on their last legs, the Sugababes are perfectly poised to take over the pop throne.
