CLEO Laine and John Dankworth appear as part of the Riverfront Theatre Music Festival on Thursday, June 2.

This formidable husband and wife team are world class performers in demand all over the world.

Their music includes jazz, classical, pop and folk.

Take a symphony orchestra, add Cleo or John - or both - and you have a recipe for excellence.

Cleo has been singing with the world's great symphonies throughout her career. Conductors with whom she has shared the platform include Pierre Boulez, Sir Adrian Boult, Sir William Walton, James Levine, David Atherton, Sir Alexander Gibson, Elgar Howarth and Jesus Lopez-Cobos.

Chamber orchestras have also collaborated with Cleo - the London Sinfonietta and The Nash Ensemble with whom Cleo recorded Schoenberg's Pierrot Lunaire a recording which earned her a Grammy nomination.

Other famous classical artistes who have performed or recorded with Cleo include guitarist John Williams, flautist James Galway, pianist Andre Previn and composer-pianist Richard Rodney Bennett who has composed several works for Cleo. Cleo's 1961 Edinburgh Festival portrayal of Anna in the Weill-Brecht opera-ballet The Seven Deadly Sins led to a London run at Sadlers Wells and later a new production with the Michigan Opera.

John Dankworth's involvement with classical music has been long and varied since leaving London's Royal Academy of Music of which he is a fellow. John instigated The London Symphony Orchestra's Summer Pops in 1985 and remained the series musical director until 1990. He has conducted 'pops' concerts of all descriptions both as a soloist and a conductor and for Cleo Laine.

Although having a wealth of classical experience, John is primarily a jazz musician and his 'pops' programmes have become widely known and respected and result in return visits to symphony halls again and again.
