Hailing from Swansea, Wales, singer Rachel K Collier first found prominence using a tune that highlighted on a favorite U.K. Television advert. “Hard Street to visit” — a quirky cover from the Jimmy Cliff traditional — appeared for the QualitySolictors industrial and premiered in 2012. Collier lent her vocals to U.K. garage area producer Wookie’s monitor “2 folks” one in the same season. She teamed up with dance manufacturer Ray Foxx and co-wrote and supplied vocals on the smash strike charting one “Boom Increase (Heartbeat)” in 2013.
