Recognised as a versatile composer, much in demand in the UK and abroad, Hesketh's works fall into contemporary classical and wind, brass and seasonal (see 'other') categories.
Contemporary Classical - Described by Tempo magazine as "...a composer who both has something to say and the means to say it”, Hesketh has received numerous commissions from international ensembles and organisations. His many concert works, including opera, orchestral, chamber, vocal and solo works are published by Schott & Co., London and are performed by leading performers, ensembles and orchestras in Europe and North America, including Sudwest Rundfunk (Baden-Baden), the BBC Philharmonic, the Royal Liverpool Philharmonic, the London Sinfonietta, Psappha, the ASKO ensemble, Ensemble 10/10, conductors Sir Simon Rattle, Oliver Knussen, Vasily Petrenko and soloists Nicholas Daniel, Clio Gould, Sarah Leonard, Hansjorg Schellenberger, Claire Booth, Sarah Nichols and Clare Hammond.
Other - Hesketh’s works for symphonic wind band have become contemporary classics of the genre (Danceries, Masque, Diaghilev Dances). Regular performances of them around the world have led to British, Japanese, American and Canadian commercial recordings. These works are frequently set as competition test pieces. Also, the catalogue of Christmas music ranges from simple congregational arrangements and shorter a cappella items to more complex original works for chorus and orchestra. Included in a growing number of carol anthologies these tuneful works receive regular performances in the UK by the Royal Liverpool Philharmonic and City of Birmingham Symphony Orchestras, as well as performances in North America and Europe.
