In the early 1990s, Kent began her professional career singing regularly at Café Boheme in London's Soho. After two or three years, Kent began opening for established jazz acts across the road at the Ronnie Scott's nightclub in London. Her album The Lyric (2006) won "Album of the Year" at the 2006 BBC Jazz Awards and was re-released on Blue Note in 2011. Kent's music has been championed by critic and jazz trumpeter Humphrey Lyttelton, and she won the 2001 British Jazz Award and the 2002 BBC Jazz Award for Best Vocalist. She has also presented jazz programmes on BBC Radio 2 and 3.
