You’ll know Kelli-Leigh’s mellifluous tones, even if her name is less familiar. Thanks to her work on dance anthems like Tiësto & Justin Caruso’s “Feels So Good” and Low Steppa’s “Runnin’”, her smooth, stylish vocals are a ubiquitous presence in clubs. But it’s her deep-house cuts with Duke Dumont that have garnered the most attention, especially the 2-steppy “Melt”, on which her voice is slowed down to a languid, sensual balm.
