Crescend'O ran for only a little while (a year or two?) in 1999. It was an aquatic circus, with diving, synchronised swimming, ice skating, horse riding and traditional circus arts, and live avent guard music (I love it and still listen to the CD sometimes) very similar to the Cirque du Soliel.
It was directed by Murial Hermene (sp?) and although not quite on the scale of CDS, it was still very good. I was very sad when it went, but between the venue opening less than half full most of the time, and a wind storm that did a large amount of damage to the tent (which they eventually repaired), it quietly went away.
Shame, I really liked it.
There are not many photos available on line as none were allowed inside. Though I still cherish my programme and CD to this day.
