"Defying convention and expanding the imaginations of participants, Oliver Beer held a choir concert under London&amp;#039;s Waterloo Station as part of the Mindful Exhibition. The angelic voices of the performers bounced and reverberated across the underground venue, turning the 200-year-old walls into an instrument of their own.  Oliver Beer is the curator of a series of acoustic experiments, collectively known as The Resonance Project, and has performed with his choir in locations around the continent: Paris&amp;#039; George Pompidou Center, Brighton&amp;#039;s sewers and a handful of monasteries. Because the sonic quality of the choirs&amp;#039; singing ranges from location to location, Beer encourages visitors to move around the group in order to find the perfect &amp;#039;sweet spot.&amp;#039; The entire process takes advantage of resonant frequencies; basically, the point at which the acoustics boom in volume due to the building&amp;#039;s design. The descriptions of audience members makes me want to check out the exhibit myself -- supposedly, it&amp;#039;s like moving through the innards of an instrument!"^^<http://www.w3.org/2001/XMLSchema#string>
