TIMED to coincide with the annual Leonid Meteor shower, the Royal Observatory in Greenwich is opening its doors after hours for Harmony of the Spheres - a performance piece created by Trinity Laban Conservatoire of Music and Dance.

Over three nights, the site will be brought to life by music and contemporary dance performances inspired by space and the heavens.

Audiences will be given a chart to guide them through the music and dance installations created among the magnificent domes, telescopes and historic rooms of the observatory.

To end the evening, audiences will choose from two finale pieces.

Heaven, composed by Edward Jessen for an ensemble of harpists, will be performed to stunning imagery of space in the Peter Harrison Planetarium, and Hell, composed by Stephen Montague, will take place outside, by the monolith.

The performances include new compositions by Trinity College of Music staff and students and works by John Cage, Berio and others.

Harmony of the Spheres is directed by multi-award winning composer Stephen Montague with movement director Lizzi Kew Ross.

It is the culmination of the Festival of Time and Space - a four week festival of science and music produced by Trinity College of Music and the National Maritime Museum as part of the UNESCO 2009 International Year of Astronomy.
