LONDON.-Fountains originally appeared on the site in 1951 as part of the Festival of Britain, when the Royal Festival Hall opened, and this summer there will be two fountains at Southbank Centre. A series of water installations by Klaus Weber are on show until 9 September and Jeppe Heins aquatic pavilion Appearing Rooms returns to the site until 16 September. The Big Giving, a fountain by the German artist, Klaus Weber, was unveiled on 14 July. In this dramatic installation six large-scale sculptures will be placed on Festival Terrace outside the Royal Festival Hall. The sculptures show the heads and hands of the artist and a number of his friends rising out of, or simultaneously sinking into, volcanic-looking mounds of rock made from industrial waste. Their heads and hands protrude from the stone and streams of water gush furiously from each of the figures, spouting from mouths, eyes, ears and armpits. Visitors will be able to walk around the figures as they variously appear to be vomiting, urinating, spitting, sweating and crying. The title The Big Giving refers to the Native North American ceremony potlach, in which the hosts status increases the more he or she gives. Webers fountain physically plays out this excess of giving and receiving, as the water gushes from one figure to another. Internationally renowned, Weber is best known in this country for his installation Public Fountain LSD Hall (2003). In the center of this piece stands a three-tiered Victorian crystal fountain filled with homeopathic LSD.
