Her trio in 2006 featured bass player Carey and drummer Mark Fletcher.
From 1996 onwards Carroll worked with Hospital Records and in 2003 toured internationally with a band formed by label owner Tony Colman that played at the Brazilian Electro Dance Music Festival in Brasilia. In the early years of the new millennium she began recording for the Splash Point label, releasing a series of superb recordings that embraced jazz, R&B and the singer-songwriter tradtion. In 2005, Carroll decided to concentrate on her jazz work and in mid-summer that year she became the first person to win two BBC jazz awards in the same year: Jazz Vocalist Of The Year and Best Of Jazz. The following year, she won the Marston’s Pedigree British Jazz Award as Vocalist Of The Year. In addition to performing, Carroll also teaches at jazz summer schools in the UK and Europe and also conducts workshops.
