NME has discovered that the voice belongs to Ghanaian-born, Nashville-based singer Ruby Amanfu. Amanfu, most well-known for being one half of the singer-songwriter team Sam & Ruby, had one of her songs nominated for a Grammy in 2007, as well as a 2003 pop single, "Sugah," that did particularly well in Europe while on the UK's Polydor Records. She appeared on Conan around this time last year, singing back-up on "Funnel of Love" with Wanda Jackson and Jack White. You can listen to Amanfu on "Love Interruption" as well as see her performing Adele's "Rolling In The Deep" on NBC's The Sing-Off after the jump.
