Today during the weeks ongoing Best Breakthrough act Live Lounge sessions Radio One has been holding all week, the wonderful Jessie Ware stepped up to perform. Now as we know by this point the Live Lounge can result in some rather odd songs being covered by artists, but today, Jessie covered something which fitted her voice beautifully. It was what she says is her "...favourite pop song of last/this year" and it originally came from Rihanna's 2012 album, Unapologetic. She covered "Diamonds" and the results were breath taking from start to finish. We've given Jessie a lot of love over the past year, and I think this just goes to show how great of a live performer she is.
