Salvator Mundi is the majestic and atmospherically rich album from saxophonist Mark Lockheart and organist Roger Sayer recorded in Temple Church, London, most recently renowned for the filming of the Da Vinci Code. More important is its beautiful acoustic, which is what, in part, inspired John Ashton Thomas (who has worked on many films including, most recently, Black Panther) to initiate this project. British jazz tyro Mark Lockheart (Loose Tubes, Polar Bear and a string of stunning and innovative albums for Edition Records) and Roger Sayer, one of the top three church organists in the UK, (but also known outside the rarified circle of great organists for playing on Hans Zimmer's soundtrack for Christopher Nolan's 2014 film Interstellar), have collaborated on this extraordinary and unique exploration of choral music and improvisation.
