Sugababes have revealed that their forthcoming album will be infused with a "darker, tougher" and "quite edgy" sound. 

The girl group performed at T4 on the Beach over the weekend, July 10, and explained to Digital Spy that although the new record isn't entirely finished, it will showcase a different style:

"We still haven't signed off on it completely yet, because it's always good to keep recording and we just want to pick the very best."

"Because we're still recording a lot, we haven't said... 'this is the sound'. 'Freedom' is a good idea of the sort of template that we're going with. It's a bit darker, tougher and quite edgy."

Watch them debut their brand new single, 'Freedom', at the event below:
