Hear a clip of Mutya Keisha Siobhan's comeback single

In one of the most anticipated comebacks of 2013 – a phrase it’s impossible to use lightly – the reunion of Mutya Keisha Siobhan is an ongoing saga that has us on the edge of our seats. They’ve finished recording their album with the pop producer of now Dev Hynes, covered Kendrick Lamar for a bit of a laugh in the process and now, finally, they’ve shared the first snippet of what will be their new single.

Flatline sounds like a big, booming pop jam full of optimism, harmonies and “ooh ohh“s supplied by Fred MacPherson of Spector. Stream a joyous one minute of it below.
