The first time Cosima spellbound us with her astonishing vocals was when she showed up on Lil Silva’s Caught Up over a year ago. The Londoner has since etched out quite a reputation with her music, and she’s back at it with a stunning single named Un-Named. Rich swelling synth lines and limber beats permeate Un-Named’s electronic & alt R&B. Despite that robust rolling opulence, there’s a supple fragility and sensual softness to Un-Named. As ravishing as the bass sturdy production is on her song, the star of the show is Cosima’s own deep, sonorous vocals, which resonate with such resounding power and confidence. Un-Named is out now via Island Records.
