She formed the ten-piece jazz fusion group Calumet with trumpeter Noel Langley and pianist Peter Churchill (including Roger Beaujolais, Ralph Salmins, and Pete Eckford) for performances at the Barbican Centre, London.
During January and February 1999, Clynes's first 'live' album was recorded at this venue, featuring pianist Liam Noble, bass player Geoff Gascoyne, and drummer Clark Tracey.
An invitation to take part in a three-week workshop with other performers from various stylistic background led to Clynes originating the role of the 'American Wife' in the opera Hotel, written by award-winning playwright Caryl Churchill and composer Orlando Gough.
A year later, Orlando Gough and Richard Chew created an eighteen piece a capella vocal group, The Shout, of which Clynes was a member with Ian Shaw, Carol Grimes, Melanie Pappenheim, Wayne Ellington, and Manikam Yogeswara.
Her jazz collaborations include lyric writing for compositions by UK musicians Django Bates, Iain Ballamy, Martin Hathaway, Anita Wardell, and American guitarist Ron Affif.
