Mabel has vivid recollections of the night before, in Isaac Rentz's dazzling promo for Let Them Know. 

The video boasts slick choreography, ultra-modern set design and a fearless performance from Mabel - all packaged in a glossy, no-holds-barred affair. 

Non-stop action from start to end, the concept oozes Noughties nostalgia, and shows a brand new side to Mabel and her performance style. She's not only singing, but definitely got the moves to go with it.
