Oliver Beer at the Lyon Biennale Review in Le Monde

[...] A second building on the same site, less frightening in its dimensions, is home to other artists - there are thirty-six at Les Grandes Locos alone - who do not suffer from the size of the place, but from being, despite their qualities, overshadowed by the spell of a video installation by Oliver Beer, a visual artist who also trained as a composer.

He invited eight singers chosen from around the world to perform in caves painted in the Upper Paleolithic in the Dordogne. Each singer chose the spot that best suited them, not for its beauty or comfort, but for the quality of the sound it echoed: a sort of natural tuning fork, to sing a song from their childhood, eight nursery rhymes from eight different cultures and languages. Everyone sings in his or her own corner, but the eight screens bring them all together in perfect polyphony. The idea of holding concerts in caves exists in many caves that can be visited, and some even believe (the hypothesis is debated) that our ancestors chose to decorate this or that part of their cave according to its acoustic qualities. Beer has given it an almost magical dimension.
