Claire has performed all over Europe and Asia with her trio and she also performs regularly with Richard Rodney Bennett in an intimate duo setting both in England and in America where they play to sell out crowds at venues including the prestigious Algonquin Hotel in New York City. Claire is also a featured soloist with the Halle Orchestra, the Royal Liverpool Philharmonic Orchestra, the RTE Concert Orchestra, the BBC Big Band and the BBC Concert Orchestra. The BBC Radio 3 programme Jazz LineUp, which she co-presents with Julian Joseph, is now in its 13th year and Claire has interviewed many of her musical heroes such as Pat Metheny, the late Michael Brecker, Brad Mehldau and Roy Hargrove.
Her 2009 album A Modern Art prompted Jazz Times USA to claim: ‘She ranks among the four or five finest female jazz vocalists on the planet.'
'The most gifted jazz singer this country has produced in twenty years.' Clive Davis - The Sunday Times
