This Thursday, St Martin-in-the-Fields, the historic church on Trafalgar Square, will be broadcasting a beautifully-presented audio-visual performance of Handel's Messiah. Part of its Fresh Horizons concert series, it features graphics from video and projection designer Nina Dunn projected onto the church's east window. Soprano Carolyn Sampson joins the Academy of St Martin-in-the-Fields and St Martin's Voices for the occasion - and you can get a flavour of the event in our exclusive preview video below.

Handel's Messiah will be broadcast on Thursday April 8 at 7.30pm (and available for 30 days afterwards). For tickets and more details visit smitf.org/fresh-horizons​
