Mutya Keisha Siobhan have revealed the eagerly awaited video for Flatline, their single out 15 September. Although the original Sugababes girls re-formed last year and have been sharing their music with their fans ever since, it marks their debut official release as MKS. The track is fresh and modern, yet features the girls' soulful voices and that unmistakable vocal blend. The video mirrors the ladies' fresh, unique talent, with colourful and blurry footage of them hanging out on an LA beach, which manages to be cool and down-to-earth all at the same time. We don't know about you, but the more we listen to this track, the more we love it! All hail MKS!
