Mis-Teeq’s relative failure to make it really big was one of music’s great mysteries (although Alesha’s recent proclamation that the other two were totally talentless might have had something to do with it). Such confidence is evident in ‘Knockdown’, an absolute pearl of a pop single. The fact that it comes straight off the Xenomania conveyer belt undermines its claims to creative genius a touch, but this is a great record in anyone’s book.
