Celeste just released a brand new album, Not Your Muse, and it's already on track to become her first No. 1 record. "Love Is Back" is the latest release, and in it her sultry, retro vocals are paired with a twinkly tune and an extremely edgy attitude. It feels like a new era for BBC's Sound of 2020, one that's decidedly more considered, more confident, and somehow more impressive, too.
