Hailing from Swansea, Wales, singer Rachel K Collier first came to prominence with a song that featured on a popular U.K. TV advert. "Hard Road to Travel" -- a quirky cover of the Jimmy Cliff classic -- appeared on the QualitySolictors commercial and was released in 2012. Collier lent her vocals to U.K. garage producer Wookie's track "2 of Us" single in the same year. She teamed up with dance producer Ray Foxx and co-wrote and provided vocals on their smash hit charting single "Boom Boom (Heartbeat)" in 2013. ~ Aneet Nijjar, Rovi
