Mutya Keisha Siobhán

Who would have thought when they formed in 1998 that, 15 years down the line, sugary pop princesses Sugababes wouldbe getting the super-hip Dev 'Lightspeed Champion' Hynes to produce their album and sampling edgy hip hopper Kendrick Lamar. Mutya Buena, Siobhán Donaghy and Keisha Buchanan, the original line-up of the pop trio, have got back together under the much more street name of Mutya Keisha Siobhan (MKS) and, if new single 'Flatline' is anything to go by, been working on their vocal harmonies. All in all, it's a pretty top-class pop comeback and one that should make for a great live show.
