Orchestrator, arranger, keyboard programmer, and vocal coach. Based in Glasgow, working across the UK and internationally.
Henry is a classically trained pianist who moved from Australia to the UK in 2012. Over thirteen years in London he built a portfolio spanning UK tours, concerts at the London Palladium and Cadogan Hall, off-West End shows, and international productions.
He recently toured the UK with Bill Kenwright's Blood Brothers as Assistant Musical Director, creating new keyboard programming still in use nationally. Other highlights include Brass and Gentlemen Prefer Blondes (both earning award nominations) and co-producing In the Wings, a web series on shows affected by COVID-19.
