Rolf Hind performs Tristan Murail's 1977 piano solo Territoires de l'oubli, recorded at the BBC's Total Immersion weekend. The work is based entirely on the instrument's natural resonances and explores gradual changes in pulse and harmonic colour. Departing from the 20th-century idea of the piano as a percussive instrument, it draws on Murail's interest in the natural overtone series. The performer is himself also a composer - interested by the resonant qualities of his instrument and a long-time advocate of new music. Many contemporary composers have written for Hind, and in 2005 he made his Carnegie Hall debut, playing music by John Adams at the composer's invitation.
