River Thames
The Water Music composed by George Frideric Handel premiered on 17 July 1717, when King George I requested a concert on the River Thames. The concert was performed for King George I on his barge and he is said to have enjoyed it so much that he ordered the 50 exhausted musicians to play the suites three times on the trip.
Liquid sound
Remann performed initial experiments with light and sound technology in 1986 at the so-called "Frankfurt Underwater Concert" in what was at that time the Central Municipal Indoor Swimming Pool (today, the "Wave" in the Hilton Hotel in Frankfurt) as an artistic performance. One of the participating musicians, among others, was Alfred Harth.
This underwater concert won Remann an entry in the Guinness Book of Records.
