Tom Service presents a special edition of the programme, featuring music recorded during the BBC Symphony Orchestra event Total Immersion: Tristan Murail. One of France's leading composers and a key composer of Spectralist music, Tristan Murail writes groundbreaking works for acoustic and electronic intruments that are both beautiful and complex in equal measure. Having studied with Olivier Messiaen, he founded Ensemble l'Itineraire and then went on to work at IRCAM in Paris. Total Immersion: Tristan Murail is the second of the the BBC Symphony Orchestra composer days, and features music from across Murail's output.
