Commissioned by homeless charity Streetwise Opera, the project was premiered at the Royal Festival Hall in London recently and is now touring venues around the world.
Here's some info from Flat-e:
My Secret Heart is a new commission by Streetwise Opera (www.streetwiseopera.org) of a music and film installation written by electronic composer and Warp artist Mira Calix, video artists Flat-e and sound designer Dave Sheppard. They worked with around 100 Streetwise performers from across the UK to create a unique work that is being shown around the world.
The new piece is inspired by the Allegri’s 17th-century choral work Miserere Mei, a piece so protected by the Vatican that they put an embargo on it. Mira Calix and Flat-e have used the theme of secrecy to explore movements and singing with Streetwise’s participants to create this new century-leaping work.
The piece exists as an immersive installation on a purpose-built 360 degree screen with surround sound and as a 7-minute film. The installation was premiered live at the Royal Festival Hall including a staging featuring a cast of 100 and is now touring to galleries, festivals and cinemas across the world through 2009 as an installation and film.
