Scottish composer Eddie McGuire’s five astronomy-inspired pieces of music have never been played before as a complete series. Tonight, to celebrate his 75th birthday, you can hear them together, with astronomer Dr Anne-Marie Heijmans of St Andrews University joining him in conversation. The music comes in three films specially recorded by musicians from the University, including trumpeter Bede Williams and members of the Wallace Collection. First comes the film Five Stars in Auriga, featuring Big Bang, Orbit, and Auriga where each instrument represents a star in the constellation. The pieces of music are interwoven with stories from the Scottish Borders of lives connected by astronomy and space. Then after a short break come Earthrise (symphonic poem for brass band) and Symphonies of Galaxies. Afterwards you can sit back with Orkney traditional musicians celebrating the occasion.
