Claire has performed worldwide with her trio and, until his death in 2012, worked extensively with the celebrated composer and pianist Sir Richard Rodney Bennett in a cabaret duo setting both in England and the US where they played to sell-out houses at venues including the prestigious Algonquin Hotel in New York City.

Claire appears as a featured soloist with the Halle Orchestra, the Royal Liverpool Philharmonic Orchestra, the RTE Concert Orchestra, the Royal Northern Sinfonia, the BBC Big Band and the BBC Concert Orchestra. Claire co-presented BBC Radio 3’s flagship jazz program ‘Jazz Line Up’ from 2000 to 2017 and interviewed many of her musical heroes such as Pat Metheny and the late Michael Brecker. Her 2009 CD A Modern Art prompted Jazz Times USA to claim: “She ranks among the four or five finest female jazz vocalists on the planet”.  

At the Queen’s Birthday Honours in June 2011 Claire was delighted to be awarded an OBE for her Services to Jazz.

Her 2019 recording Believin’ It will be with her brand new all-Swedish trio and her twentieth album release. The quartet will tour throughout the UK during May and June.
