Lloyd Moore was born in London and started composing at the age of 11 after encountering the music of Debussy and Stravinsky at school. He studied composition at Trinity College of Music, where he was awarded the Chappell Prize for Composition and the Ricordi Prize for Conducting, and at King's College London where he obtained his Masters degree with Distinction. His teachers have included Simon Bainbridge and George Benjamin.
His earliest recognised work is Divine Radiance for large ensemble, originally composed in 1989 but substantially rewritten during 1996-7. This revised version was premiered by the London Sinfonietta at London’s Queen Elizabeth Hall in 1999, garnering much critical praise.
Subsequent works include Quint (2001) for five players which has become one of Lloyd’s most frequently played pieces receiving numerous performances as well as broadcasts on BBC Radio 3, Swiss Radio and the ABC in Australia; Three Epigrams of Kathleen Raine (2006) for mezzo-soprano and ensemble, premiered at the Queen Elizabeth Hall by Louise Mott and members of the Philharmonia Orchestra; Diabolus in Musica (2007) for orchestra, first performed by the BBC Symphony Orchestra; Scherzino (2008) for piano, commissioned by the BBC for the Mendelssohn bicentenary (subsequently incorporated into the Suite for piano) and the song-cycle Charms To Music (2010). More recent works include Cascara for orchestra (2014-15) and Airs and Arabesques (2015) for solo clarinet. His works have been featured at the Cheltenham, Hampstead & Highgate, Huddersfield, Norfolk & Norwich and Presteigne Festivals among others and performed by such ensembles as the Emperor Quartet, Psappha and London Sinfonietta, artists such as Charmian Bedford, Iain Burnside, Peter Cigleris, Alice Neary, Matthew Schellhorn, Philip Sheppard, Ailish Tynan, Tamsin Waley-Cohen, Huw Watkins, Nathan Williamson, Alexandra Wood and Andrew Zolinsky and the conductors Christopher Austin, Martyn Brabbins, Nicholas Kok, Diego Masson and André de Ridder.
Lloyd’s musical interests and influences are wide and varied: the music of the early 20th-century remains an important source of inspiration, though he cites later figures such as Messiaen, Ligeti and Maxwell Davies as important too. He lives and works in London.
He also works as a freelance music editor and copyist. He has been involved in arranging and orchestration work and is an experienced conductor.
